Version 1.3-a
-------------
Antoine de St-Exupéry asserted that elegance in engineering is
achieved not when there is nothing left to add, but when there is
nothing left to take away.

By those standards, mom is a Rube Goldberg contraption.  She was
created over the years while groff, and my understanding of it,
changed and evolved.  However, I'm a firm believer in "if it
ain't broke, don't fix it," so I'm leaving any major clean-up
of redundancies and whatnot for a rainy day.

Inasmuch as possible, macros that turn a feature on or off follow
a similar style.  Invoking the macro without an argument turns
the feature on.  Invoking it with any other argument turns it off.
Use of the argument OFF is recommended, but not required; users
may find other conventions preferable (e.g. NO, X, END, QUIT, etc.).

"<anything>" in the description of arguments that can be passed
to a macro means that any argument turns the feature off.

About the warn level
--------------------

There's a lot of testing for the presence of number registers and
strings in this macro file.  Many of the registers and strings
pop into and out of existence on the fly.  For convenience, I
often use

    .if \\n[whatever]    and    .if !\\n[whatever]

to test "if the register exists and is (not) empty."  Groff,
encountering such tests when called with the -ww options, emits

    warning: number register whatever not defined.

Groff also warns about strings similarly tested for.

The warn level, above, is high in order to shut off those
warnings.  If you're futzing in this file and need more verbose
warnings, either comment out ".warn 8192" or set the warnlevel
to the one you need (but be ready for lots of what I've just
described).

\# +++PAGE LAYOUT+++
\#
\# Macros that control the physical layout of the page: paper size
\# and margins.
\#
\# PAGE WIDTH
\# ----------
\# *Argument:
\#   <width of printer sheet>
\# *Function:
\#   Stores user supplied page width in register #PAGE_WIDTH.
\# *Notes:
\#   #PAGE_WIDTH is used to establish the default LL (and right margin).
\#   Requires unit of measure.

\#
\# L_MARGIN
\# --------
\# *Argument:
\#   <offset from page left>
\# *Function:
\#   Stores user supplied page offset in register #L_MARGIN.
\#   Sets .po to user supplied offset.
\# *Notes:
\#   Requires unit of measure.

\#
\#
\# R_MARGIN
\# --------
\# *Argument:
\#   <width of right margin>
\# *Function:
\#   Stores user supplied right margin in register #R_MARGIN.
\# *Notes:
\#   This is a pseudo-margin.  Right margin is actually a function of
\#   line length.  The macro calculates line length from the page offset
\#   and the value plugged into #R_MARGIN.
\#
\#   N.B. -- PAGEWIDTH and L_MARGIN have to be defined before R_MARGIN.
\#
\#   Requires unit of measure.

\# T_MARGIN
\# --------
\# *Argument:
\#   <distance to advance from top of page>
\# *Function:
\#   Stores the user supplied top margin in register #T_MARGIN.
\#   Advances user supplied depth from the top of the page.
\# *Notes:
\#   Requires unit of measure.

\# PAGE
\# ----
\# *Arguments:
\#   <pagewidth>  [pagelength [leftmargin [rightmargin [topmargin [bottommargin]]]]]
\# *Function:
\#   Page set-up.  Collects arguments and passes them to the appropriate
\#   macros.
\# *Notes:
\#   All arguments after pagewidth are optional, but must appear
\#   in the order given above.  (User can fill in as much or as
\#   little as desired.)

\# +++FAMILY AND FONT+++
\#
\# FALLBACK FONT
\# -------------
\# *Argument:
\#   <fallback font> [ ABORT | WARN ] | ABORT | WARN
\# *Function:
\#   Sets register #ABORT_FT_ERRORS to 1, or defines a fallback font
\#   called "dummy" at font position 0.
\# *Notes:
\#   Calls to non-existent families cause mom to continue processing
\#   files using the fallback font until a valid family is entered.
\#
\#   Calls to non-existent fonts generate warnings.  If ABORT is passed
\#   to FALLBACK_FONT, mom stops processing files after the warning.
\#   Otherwise, she continues to process files using the fallback font
\#   after the warning is issued.  The default fallback font is CR; the
\#   default for font warnings is to abort.

INLINE KERNING AND HORIZONTAL MOVEMENT
--------------------------------------
Kerning

Inline kerning provides a simple method for users to adjust the
amount of space between any two letters.  It's predicated on a
unit of measure "U", which is 1/36 of the current point size as
returned by \n[.ps].  E.g., if the current point size is 18,
\n[.ps] returns 18000u, therefore U=500u.  Since U remains
proportional relative to the current point size, the amount
of kerning between two letters as expressed in Us remains
visually similar regardless of changes in point size.

N.B.--the amount of inline kerning supplied by \*[BU<n>] or
\*[FU<n>] is added to or subtracted from any kerning that already
takes place between two characters when automatic kerning is
turned on.

In groff v. 1.17.2, it was not possible to pass arguments to macros that
were called with inline escapes, nor thence to evaluate conditional
expressions.  Consequently, each pseudo-escape \[BU<n>] had to be defined
separately with ".char".

As of v. 1.18, one can pass arguments to inline strings/macros,
hence it is now possible to do \*[BU n] where n, inline, is the desired
number of kern units.  The original .char definitions have been left in
for backward compatibility with documents created prior to mom-1.1.3c.

\# WHOLE LINE KERNING (RW and EW)
\# -----------------------------
\#
.ig
The line kerning macros are special instances of track kerning,
used where a complete line needs to be tightened (or relaxed) in
order to accomodate or remove one or two more characters
than the default justification permits.
..
\#
\# *Argument:
\#   <amount of overall "kerning" (letter spacing) to apply to the line>
\# *Function:
\#   Invokes .tkf (track kerning) for the current font with
\#   1 as both the upper and lower point size limits, so that
\#   the value entered by the user applies regardless of point
\#   size.  RW ("Reduce Whitespace") reduces the amount of space
\#   between all characters by an equal amount.  EW ("Extra
\#   Whitespace") increases the amount of space.
\# *Notes:
\#   Decimal values are acceptable.
\#
.ig
The groff documentation is a tad confusing about what unit of
measure is used in track kerning, only that the width of each
character is increased or decreased by the amount(s) passed as
arguments to .tkf, and something about linear function of point
size.  In fact, with the way I've put this macro together, it
doesn't matter.  All the user needs to know is that a value of
one will produce an unacceptably tight or loose line at most text
point sizes; therefore, effective use of RW and EW is in the
fractional range below 1 (e.g. .25, .5).  Given that RW and EW
are for massaging type, a certain amount of experimentation and
previewing is expected and necessary.

\n(.f holds the current font number, which is acceptable to .tkf.

RW and EW must be reset to 0 to cancel their effect on subsequent
output lines.
..

\# BREAK AT LINE KERN
\# ------------------
\# *Arguments:
\#   toggle
\# *Function:
\#   Enables/disables .br's before .RW and .EW
\# *Notes:
\#   Mostly, users will want .br's before any kind of line kerning, but
\#   there may be cases where they don't.  BR_BEFORE_LINE_KERN is off by
\#   default and must be invoked explicitly.

\# ----------------
\# *Arguments:
\#   <none> | <anything> | DEFAULT
\#                 or
\#   LINES <n> | MARGIN <n> | SPACE <n>
\# *Function:
\#   Turns auto hyphenation on or off, resets the hyphenation style
\#   to default, or permits the setting of various hyphenation
\#   parameters.
\# *Notes:
\#   HY, by itself, defaults to .hy 14, i.e. no hyphens after the
\#   first two or before the last two characters of a word, and no
\#   hyphenation of the last line prior to a trap (e.g., at the
\#   bottom of a page).
\#
\#   HY DEFAULT resets the hyphenation style to .hy 14 (see
\#   above) if that behaviour is desired after changes have been
\#   made to LINES, MARGIN, or SPACE.
\#
\#   HY LINES <n> sets the number of allowable consecutive hyphenated lines.
\#
\#   HY MARGIN <n> sets the amount of space (ipPcm) allowed at the end
\#   of a line in QUAD mode before hyphenation is tripped (e.g. if there's
\#   only 6 points left, groff won't try to hyphenate the next word).
\#
\#   HY SPACE sets the amount of extra interword space (ipPcm) that can
\#   be added in JUSTIFY mode to prevent a line from being hyphenated.

\# LEFT, RIGHT, AND CENTER
\# -----------------------

.ig
The purpose of these macros is to allow the user to enter lines of
text that will be quadded LRC *without* the user having to enter .BR
or .br between lines.  For the sake of consistency, all three appear
to behave similarly (from the point of view of the user), although
the underlying primitives don't.  For this reason, LEFT, RIGHT, and
CENTER must be followed by .QUAD [L R C J] or .JUSTIFY to restore
text to groff fill mode.

\# LEFT
\# ----
\# *Argument:
\#   <none>
\# *Function:

\#   not be broken, just continued (indefinitely) until a return is
\#   encountered.  Note that this behaviour differs from the RIGHT and

\# +++TABS+++
\#
.ig
There are two different kinds of tabs available: typesetting tabs
and string tabs.

Typesetting tabs are set with TAB_SET, which requires a tab number,
an indent (offset) from the left margin and a length (optionally
with a quad direction and an instruction to fill lines).  After tabs
are set with TAB_SET, they are called with .TAB n, where "n"
corresponds to the number passed to TAB_SET as a valid tab number.

String tabs allow the user to mark off tab positions inline.  Tab
indents and lengths are calculated from the beginning and end
positions of the marks.  Up to 19 string tabs may be created,
numbered 1-19.  Once created, they are called with .TAB n,
just like typesetting tabs.

Setting up string tabs is a two-step procedure.  First, the user
enters an input line in which s/he wants to mark off string tabs.
The beginning of a tab is marked with \*[STn], where "n" is
the desired number of the tab.  The end of the the tab is marked
with \*[STnX].  All ST's must have a matching STX.  String tabs
may be nested.

Next, the user invokes .ST n for every string tab defined, and
optionally passes quad information to it.  That done, string tabs
can be called just like typesetting tabs.

String tabs don't preview properly with gxditview.  Use gv instead.

\# QUAD AND SET STRING TABS

\# *Arguments:

\# *Function:
\#   Creates strings $ST<#>_QUAD_DIR and $ST<#>_FILL, then sets up a
\#   tab based on the collected information.
\# *Notes:
\#   Like TAB_SET, ST invoked without a quad direction will default to LEFT.

\# TAB SET
\# -------
\# *Arguments:
\#   <n>  ident(ipPcm)  length(ipPcm)  [L | R | C | J [QUAD]]
\# *Function:
\#   Creates macros TABn and TAB n, where "n" is any arbitrary number.
\#   TABn is a typesetting tab (i.e. a tab defined as an indent
\#   from the page left offset plus a line length.)
\# *Notes:
\#   n      = arbitrary digit to identify the tab
\#   indent = indent from left margin; unit of measure required
\#   length = length of tab (unit of measure required; can be
\#            \w'<string>'u--if more than one word in string, surround
\#            with double quotes "\w'<three word string>'"
\#   LRCJ   = quad for tab (left, right, center, justified)
\#            If option QUAD afterwards is not given, quad is line for line
\#            (no fill mode), meaning that there's no need for .BR or .br
\#            between lines.
\#   QUAD   = fill tab (so it behaves as if .QUAD LRC or .JUSTIFY
\#            had been given).
\#
\#   N.B. -- indents *must* be turned off before setting tabs
\#
.ig
Examples:
--------

.TAB_SET 1 2P+6p 12P C

means "create a tab numbered 1 that starts 2 picas and 6 points from
the left margin, is 12 picas long, and centre each input line."

.TAB_SET 1 2P+6P 12P C QUAD

means exactly the same thing, except that input lines are joined and
the area delimted by the tab filled with centered text.

TAB n can be called at any time after being set.

Tabs are NOT columnar in behaviour.  If the text inside a
tab runs to several lines, when you call the next tab a break
occurs, meaning that the new tab starts one line below the last
line in the previous tab.  For columnar behaviour, you must
use the multi-column macros in addition to tabs.

If you want tabs to line up bottom-line to bottom-line (most likely
single line tabs), use .TN (provided the tabs are numbered sequentially).
Otherwise, you must use .EL then .TAB <n> if you want them to align.

If you want to reset tabs, you must use .TQ before .TAB_SET.

Note that indents are turned off automatically whenever a new
tab is called with TAB <n>.

Tabs themselves are user-invoked using the TAB macro with a numeric
argument, e.g. TAB 1.

Generally, in order not to get confused, it's a good idea
to make sure all indents are off before setting tabs.

\# UNDERSCORE
\# ----------
\# *Arguments:
\#   [points below baseline] "text"
\# *Function:
\#   Places an underscore 2 points under the string if no lead given,
\#   otherwise places underscore under string by user specified amount.
\# *Notes:
\#   When using this macro, the string to be underscored must begin
\#   with double-quotes ("), regardless of whether it's the sole
\#   argument or the second.
\#   E.g.:
\#      .UNDERSCORE "Text to be underscored
\#         or
\#      .UNDERSCORE 2p "Text to be underscored
\#
\#   All text is underscored (including punctuation and spaces).
\#   This is the primary difference between UNDERLINE and UNDERSCORE,
\#   aside from the fact the UNDERLINE only works with Courier.
\#
\#   UNDERSCORE does not work across line breaks.  Each line of
\#   text must be entered separately with UNDERSCORE.  If the
\#   UNDERSCORE begins in the middle of a line and crosses over a
\#   break, the portion before the break must be entered in its own
\#   UNDERSCORE, as must the portion that comes after the break.

\# ---------------
\# *Arguments:

\# *Function:

\#   new point size (for character width) from arg, and defines string
\#   COND or EXT, which set the type size to the new character width,
\#   and sets the height of type to the value stored in CURRENT_PT_SIZE
\# *Notes:
\#   CONDENSE_OR_EXTEND is invoked from the aliases
\#   CONDENSE and EXTEND.  CONDENSE implies <100, EXTEND
\#   implies >100.  Do not use a percent sign in the argument.
\#
\#   There is no default setting for CONDENSE or EXTEND.
\#   80 is a good approximation of condensed type, 120 is okay
\#   for extended.
\#
\#   The value set by CONDENSE or EXTEND applies to all
\#   subsequent \*[COND] or \*[EXT] escapes until a new value is set.
\#
\#  \*[COND] or \*[EXT] must be turned off before all changes of point

The leader mechanism is primitive, but it works.  Basically, every
macro in this set that includes a line length also sets a single
groff tab stop at the right hand end of the line.  That way,
whenever Ctrl-A is invoked (always at the end of an input line),
leader of the correct length gets deposited.  Ctrl-A is accessed by
the string LEADER (i.e. inline, as \*[LEADER]).  Leaders within tabs
get their length from the tab line length.

\# DROP CAP
\# --------
\# *Arguments:
\#   <dropcap letter> <# of lines> [COND <% to condense> | EXT <% to extend>]
\# *Function:
\#   Calculates point size of dropcap based on # of lines passed as
\#   arg 2.  Sets indent for text based on dropcap width+gutter.
\#   Advances and prints dropcap; reverses and prints indented text
\#   to bottom of dropcap, then resets indent to left margin (plus
\#   any indent that was in effect prior to invoking DROPCAP).
\# *Notes:
\#   Drop caps put a strain on on resource-challenged systems.
\#
\#   Drop caps when using the doc processing macro PP only work with
\#   initial paragraphs (i.e. at doc start, or after heads), only when
\#   DROPCAPS comes immediately after PP, and only when the PRINTSTYLE
\#   is TYPESET.  If these conditions aren't met, DROPCAPS is silently
\#   ignored.
\#
\#   The COND or EXT argument are processed separately from all
\#   other COND or EXT inlines or macros, hence passing COND or
\#   EXT has no effect on running type.

\# +++INDENTS+++

.ig
There are five styles of indents: left, right, both, temporary,
and hanging.  Each is set/invoked with a different macro.
Indent macros begin with the letter "I", hence .IL means "indent left,"
.IR means "indent right," and so on.

The first time any of the indent macros is used, it requires an
argument--the size of the indent (with a unit of measure).  The
size may also be entered using the \w escape--very useful
for numbered lists using HI.  The unit of measure is required.
Subsequent invocations don't require the argument; the indent
measure remains the same until it's changed by invoking the macro
with an argument again.

If no indents are in effect, the arguments passed to indent macros are
measured from the left and right margins of the page.  If a left indent
or a right indent is already in effect, the arguments passed to
the indent macros are calculated from the current values; in other words,
the arguments are additive.  If you quit an indent and later return
to it, its value will be the value last in effect, unless you pass
it an argument.  If you do pass an argument, it is added to the last
value in effect, unless you cleared the indent with one of
.I<LRB>X/Q macros.

Example
-------

.IL 2P
...some text...
.IL 2P
...some text...
.IQ
...some text...
.IL
...some text...

The first .IL 2P indents text 2P from the left margin.  The second
.IL 2P indents text by an additional 2P, i.e. 4P from the left margin.
.IQ turns the indent off.  The last .IL (which has no argument)
takes its value from the total of all arguments passed to .IL (in
this case, 2P and 2P), therefore it indents 2P+2P from the left
margin, i.e. 4P.  If you wanted the last .IL to indent just 2P,
you'd either have to reset the .IL prior to .IQ (.IL -2P), or pass
the last .IL the argument 2P.

To reverse the sense of an indent added to an indent, you may use
negative values.

Indents can be turned off individually with ILX, IRX, and IBX.
LEFT and RIGHT indents may be combined and manipulated
separately, (e.g. you can have an IL of 2P and an IR of 4P
operative at the same time, and then change, say, the IL to
4P--thereby left indenting 6P--while the IR remains at 4P.

IB automatically turns off IL and IR.  They have to be reinvoked
again when needed. IL and IR automatically turn IB off; it, too,
has to be reinvoked with needed.

All indents can be turned off at once with IQ.  The ILX, IRX, IBX,
and IQ macros simply turn the indents off; the values stored in
the respective indent macros (IL, IR, IB) remain in effect.  If
the user wishes to clear the values, the I<LRB>X macros should be
invoked with the single argument CLEAR.  IQ CLEAR clears out
the values stored for all indent styles.

Indents *must* be turned off before settting string tabs
inside PAD.  Generally, in order not to get confused, it's a
good idea to turn all indents off before setting any tabs.

TI and HI are special cases.  There's no need to turn them off,
since they affect only one line--the first after their
invocation.  Like the other indent styles, the first time
they're invoked, they require a value in iPpcm; each subsequent
invocation without an argument will use the same value.  To
change the value, simply pass a new value.  Values for TI and HI
are *not* additive.

HI presupposes that you already have a left or both indent on.
HI will never hang a line outside the left margin of a document
or column.  In other words, you must have IL or IB on before you
can use HI.

\# TYPE-STYLE CONTROL MACROS

.ig
The control macros for family, font, size, quad and color are here
grouped together.  Each (e.g. _FAMILY or _FONT) tests for a calling
alias before performing the action(s) appropriate to the calling
macro.  Defaults for all these guys are set in DEFAULTS, and listed
in the "Control Macros" section of the documentation pertinent to
the macro whose style is to be changed.

\# +++START THE DOCUMENT+++
\#
\# THE START MACRO
\# ---------------
\# *Arguments:
\#   <none>
\# *Function:
\#   Reads in default document style parameters and any parameter
\#   the user has changed before issuing START.
\#   Using the information gathered in the opening macros,
\#   prints appropriate title (or chapter #), subtitle, author
\#   and document type (if appropriate).
\# *Notes:
\#   The .PRINT \& (zero-width character) is required to get the
\#   subsequent .sp request to work as advertised.
\#
\#   The overall document line length, family, and point-size
\#   are stored in #DOC_L_LENGTH, $DOC_FAM, and #DOC_PT_SIZE for
\#   use in the HEADER and FOOTER macros.
\#
\#  First, define some strings for point sizes

\# *Function:
\#   Turns printing of document header on or off.  If a second argument
\#   in units of measure is given, advances that distance from the
\#   top of the page without printing the document header.
\# *Notes:
\#   Default is on.  If the 1st argument is <anything> (which turns
\#   document headers off), the optional 2nd argument may be given
\#   (with a unit of measure).

\# *Function:
\#   Creates or modifies register #DOC_LEAD.  If the optional
\#   ADJUST argument is given, adjusts leading so that the last
\#   line of text falls exactly on #B_MARGIN.
\# *Notes:
\#   DOC_LEAD is the basis for calculating all leading changes in
\#   a document.  Default for TYPESET is 16; 24 for TYPEWRITE.
\#
\#   Because the visible bottom or footer margin of a page depends
\#   on the overall document lead supplied by the register #DOC_LEAD,

\# *Notes:
\#   #EPIGRAPH 1 = centered; 2 = block
\#
\#   By default, epigraphs are centered, allowing the user
\#   to input them on a line per line basis.  To change this
\#   behaviour, the user can supply the argument BLOCK, which
\#   will produce indented, filled text similar to BLOCKQUOTE.
\#
\#   If a block epigraph contains more than one para, ALL paras of
\#   the epigraph must be preceded by PP.  Otherwise, PP is optional.

\# *Notes:
\#
.ig
Typically, the author string appears at the left of header/footers,
and the title string appears at the right.  This switches the
location of the two.  Useful in conjuction with RECTO_VERSO to tweak
switches on alternate pages to come out as the user wishes.  The
assumption of RECTO_VERSO is that the first page of the document
(recto) is odd, and even though it has no header/footer, if it did
have one, it would print as AUTHOR...CENTER...TITLE (or whatever
strings the user has supplied for HDRFTR_LEFT/RIGHT), meaning that
the next page, which does have a header/footer, will come out as
TITLE...CENTER...AUTHOR (or whatever strings the user has supplied
for HDRFTR_LEFT/RIGHT).  SWITCH_HDRFTRS allows the user to get the
desired string in the desired place on the desired recto/verso page.

Default is OFF.

\# -------------------------
\# *Arguments:
\#   L | LEFT | C | CENTER | CENTER | R | RIGHT <hdrftr_recto_string>
\# *Function:
\#   Toggles #USERDEF_HDRFTR on, stores quad as #USERDEF_HDRFTR_RECTO_QUAD,
\#   stores string in $USERDEF_HDRFTR_RECTO.
\# *Notes:
\#   For use when users don't want 3-part headers/footers, but rather
\#   want to design their own headers/footers and need different
\#   headers/footers on recto and verso pages.  Using just
\#   HEADER_RECTO, even when recto/verso is not on, allows users to
\#   design their own headers/footers for doc pages.

\# ------

\# *Notes:
\#   In order to convert the title string to caps in the header (in the
\#   event that the user enters .TITLE in caps/lc), I've used
\#   quad left, quad centre, and quad right to arrange the three bits
\#   of the header, rather than .tl.  This allows the use of the CAPS macro.
\#   The downside is that I have to add \\v'-(\\n[#LEAD]u*<n>) in order
\#   for -Tlatin1 output to align the header/footer strings on the baseline.
\#   The console output still isn't brilliant, but at least it's
\#   comprehensible.

\# ---------
\# *Arguments:

\# *Function:
\#   Figures out what to do with paragraphs under differing conditions.
\# *Notes:
\#   For the time being, there's no automatic widow/orphan control.
\#   Controlling them isn't just a matter of establishing an arbitrary
\#   number of lines needed for a para, since groff doesn't then
\#   handle single line paragraphs gracefully.  Usually, the whole
\#   page needs to be tweaked.
\#
\#   Note the use of transparent line break (\!.br) to get
\#   PP to work within blockquotes and epigraphs.
\#
\#   PP_STYLE 1 = regular paras; 2 = blockquotes, epigraphs

\# -----
\# *Arguments:
\#   <none> | <anything>
\# *Function:
\#   Indents quoted text on a line for line basis, or turns QUOTE off.
\# *Notes:
\#   Owing to the need to bottom align TYPESET pages, quoted text gets
\#   diverted so its depth can be measured (in DO_QUOTE) for determining
\#   how much space to put before and after.

\# DO QUOTE
\# --------
\# *Arguments:
\#   <none>
\# *Function:
\#   Ends the diversion P_QUOTE or B_QUOTE.  Spaces them according to
\#   PRINTSTYLE, whether there's inter-paragraph spacing, and page
\#   position.  TYPEWRITE treats spacing the same way in all circumstance
\#   (viz. an extra line space).  TYPESET puts in only half
\#   line spaces if the entire quote plus 1 line of body under the quote
\#   fits on the the page; otherwise it puts in a full extra blank
\#   line.  (This is to ensure the page remains bottom aligned).

\# BREAK QUOTE

\# *Arguments:

\# *Notes:
\#   Because quotes go into a diversion before they're output,
\#   footnotes in quotes that cross pages behave erratically.  The footnote
\#   isn't processed until the diversion ends, hence the footnote
\#   marker in the quote isn't always correct for the new page (it's
\#   picked up from the old one).  BREAK_QUOTE is a workaround for
\#   this problem.

Mom's footnote handling is baroque, to say the least.  There are
redundancies in a number of the macros involved, as well as some
registers that probably don't get used anymore.  The baggage is left
in in case some new footnote oddity/challenge gets thrown my way.

The macros are heavily commented.

\# FOOTNOTE
\# --------
\# *Arguments:
\#   <none> | INDENT  L|LEFT|R|RIGHT|B|BOTH  <indent value> | <anything>
\# *Function:
\#   Begins collecting and diverting footnote text if no argument
\#   given.  Otherwise, ends diversion FOOTNOTES, measures footnote
\#   depth, and sets footnote trap.
\# *Notes:
\#   The input line preceding a footnote call MUST terminate with \c
\#   or the footnote marker will be spaced away from the word it
\#   should be joined to.
\#
\#   If FOOTNOTE is invoked with INDENT, the footnote will
\#   be indented.  An indent style and an indent value must be given.
\#   Subsequent footnotes will NOT be indented; INDENT must be given
\#   for each footnote the user wants indented.

\# The main macros that handle footnote processing.
\# -----------------------------------------------
\#
.ig
Sometimes, #VARIABLE_FOOTER_POS sets FOOTER at a location that gives
the impression another line of running text could fit on the page.
VFP_CHECK is always set to the line just above the one where FOOTER
will be sprung, and checks for this condition.  If it exists, FOOTER
is set one line lower on the page, thus squeezing in an extra line
of running text.  This is a judgment call on my part, but seems to
work well.  If there are problems (e.g. footnotes really do look
jammed), the user should probably adjust FOOTNOTE_AUTOLEAD and/or
FOOTNOTE_RULE_ADJ.

The macro has to be run in its own environment, otherwise the first
word of the last line before the footnotes gets chopped.

FN_OVERFLOW_TRAP starts off "underneath" FOOTER, but is revealed
as #VARIABLE_FOOTER_POSITION changes the position of FOOTER.
FN_OVERFLOW_TRAP simply starts diversion FN_OVERFLOW to "catch"
the overflow.  The diversion is ended in FOOTER, immediately after
FOOTER outputs the diversion, FOOTNOTES, before PROCESS_FN_LEFTOVER
is run (either in HEADER, or in FOOTER if moving col to col).

When endnotes are output, the spacing between the notes is always
1 extra linespace.  This can have bottom margin consequences.  If
this doesn't bother you, don't worry about it.  If it does bother
you, and you want to adjust the spacing between any two endnotes (as
they're output), make the spacing adjustments (.ALD/.RLD) at the
*end* of endnotes (i.e. just before .ENDNOTE OFF), not at the top.

Endnotes must be output manually with .ENDNOTES. This allows user
the flexibility to output endnotes at the end of each collated
document, or to output them at the end of the entire document.

\# Control macros
\#
\# ENDNOTE POINT SIZE
\# ------------------
\# *Argument:
\#   <base point size for endnotes>
\# *Function:
\#   Creates or modifies register #EN_PS.
\# *Notes:
\#   Default is same as running text in body of document.
\#
\#   This size control macro differs from other size control macros
\#   in that it sets an absolute point size, not a relative one.  This
\#   is because a) endnotes always appear separate from the body of
\#   a document and therefore don't need to be relative to the body
\#   of the document, and b) there are quite a few elements of the
\#   endnotes page(s) that need to be relative to the base point size
\#   of that page.  If the base endnote point size were relative to
\#   the body of the document (i.e. a _SIZE macro taking a +|- value)
\#   getting the rest of the endnote elements sized properly could
\#   become very confusing.

.ig
Mom treats bibliographies and endnotes very similarly.  The chief
difference is that endnotes are collected and formatted inside a
diversion, while bibliographies are built "by hand."  ENDNOTES sets
up the endnotes page and outputs the formatted diversion.
BIBLIOGRAPHY sets up the bibliography page, then awaits refer
commands.

All of the bibliography control macros have their exact
counterparts in the endnotes control macros.  It was tempting to do
fancy stuff with aliases to avoid the repetition, but for reasons
of my own sanity, and for the benefit of anyone wanting to play
around with the bibliography control macros, I decided to keep them
separate.

Because the bibliography control macros all have endnotes
equivalents, refer to the appropriate, similar endnote macro for
Arguments, Function and Notes.

\# Style for outputting collected bibliographic references

\# *Function:
\#   Sets #BIB_LIST to 1 for numbered list style, 0 for plain output
\# *Notes:
\#   Technically, user is supposed to enter PLAIN if s/he wants an
\#   unumbered bibliography, but the el clause says "any arg but
\#   LIST means unumbered."  Effectively, any arg but LIST produces
\#   a "plain" bibliographic list.

\#   The 2nd and 3rd args have the same options as the 2nd arg to LIST.

\# *Function:
\#   Creates or modifies register #TOC_PS.
\# *Notes:
\#   This size control macro differs from other size control macros
\#   in that it sets an absolute point size, not a relative one.
\#   See notes for ENDNOTE_PT_SIZE for explanation.  No unit of

\# APPEND AUTHOR(S) TO TOC DOC TITLE ENTRIES
\# -----------------------------------------
\# *Argument:
\#   <none> | <name(s) of author(s) as they should appear in toc doc title entries>
\# *Function:
\#   Creates register #TOC_AUTHORS (to tell TOC to append authors
\#   to toc doc title entries).  Optionally creates string
\#   $TOC_AUTHORS.
\# *Notes:
\#   Normally, TOC does not append the author(s) to a toc doc title
\#   entry.  This special macro instructs TOC to do so.
\#
\#   If user has multiple authors for each doc when collating,
\#   TOC_APPENDS_AUTHOR "<string>" must be inserted somewhere between
\#   COLLATE and START in each doc.  Otherwise, mom prints only the
\#   first author given to AUTHOR.

\# NUMBER QUOTE AND BLOCKQUOTE LINES AS PART OF RUNNING TEXT
\# ---------------------------------------------------------
\# *Argument:
\#   <gutter> | <anything>
\# *Function:
\#   Sets #(B)QUOTE_LN to 1 if no argument, or a single numeric
\#   argument, is given; otherwise, turns (BLOCK)QUOTE linenumbering
\#   off.
\# *Notes:
\#   #(B)QUOTE is checked for in QUOTE and BLOCKQUOTE.
\#   The single numeric argument allows establishing a different gutter from
\#   the one used for line numbers in running text.

The following strings define the order of entries for different
types of references.  Each letter in the string refers to a database
field (A for author, T1/T2 for article and book titles, etc).
Mom is set up for MLA-style bibliographies.  Other styles can be
implemented here by re-ordering the fields.

Correct MLA "typewritten" style (printstyle TYPEWRITE) demands
two spaces after each period.  The spaces are hardwired into the
string definitions (ref*add-<x>), so we have to make sure that there
aren't two spaces when the printstyle is TYPESET.  Since I find that
references look a bit crowded with 0 sentence space, I've bumped it
up to +4.  User's sentence spacing is reset in FOOTNOTES and ENDNOTES.
