2023-01-24  G. Branden Robinson <g.branden.robinson@gmail.com>

	Regression-test Savannah #54909.

	* tests/P-indentation-works.sh: Do it.
	* mm.am (mm_TESTS): Run test.

2023-01-24  G. Branden Robinson <g.branden.robinson@gmail.com>

	* m.tmac (df@print-float): Eliminate spew at high debug levels.
	This macro gets called even when there aren't any floating
	displays pending, so we cannot assume that related registers are
	defined.

2023-01-24  G. Branden Robinson <g.branden.robinson@gmail.com>

	* m.tmac (P): Fix missing backslash after brace escape sequence.
	Problem introduced by me in 3b1afbdb8e, 6 January.

2023-01-22  G. Branden Robinson <g.branden.robinson@gmail.com>

	* m.tmac: Help user navigate the document type macros.  Stop
	setting up the formatter to throw "unrecognized macro"
	diagnostics for macros that are plainly documented in
	groff_mm(7).
	(@disable): New macro takes a list of macros whose definitions
	are replaced with a warning diagnostic about how they're no
	longer unavailable due to use of another document type macro
	already called, identified by new string `@cover`.
	(TL, MT, COVER, LT, LO): Define `@cover` and call `@disable`.
	Drop existing diagnostics that did a similar thing as above,
	more verbosely.

2023-01-17  G. Branden Robinson <g.branden.robinson@gmail.com>

	* m.tmac: Revise diagnostic messages.  Use a consistent message
	format, including a space after a colon and the name of the
	complaining macro.
	(pg@header): Drop unnecessary empty comment at end of macro
	call.  Macro call syntax differs from `ds` request syntax.
	(2C, MC, FD, FS, FE, DF, LB, LI, LE, LC, AL, ML, VL, BL, DL, RL)
	(BVL, TH, TE, PS, B1, B2, APPSK, AS, SETR, GETST, GETHN, GETPN)
	(INITI, IND, LT, LO): Refer to self with `\$0` string instead of
	a literal.
	(2C, MC, PS): Throw fatal error immediately instead of doing
	other processing first.
	(2C, MC, FD, FS, FE, DF, ds@set-format, ds@end, LB, LI, LE, LC)
	(AL, ML, VL, BL, DL, RL, BVL, TH, TE, B1, B2, APPSK, AS, SETR)
	(GETST, GETHN, GETPN, INITI, IND, let*lt-sign, LT, LO): Stop
	unnecessarily quoting arguments to @error macro.
	(FD, LB, VL, BVL, APPSK, SETR, GETST, GETHN, GETPN, INITI):
	State quantities of expected and actual arguments.
	(FS, FE, LC, B1, INITI): Clarify message.
	(DF, DS): Store macro name in `ds@macro` for use in later
	diagnostics thrown by internal macros.
	(DS): Drop dead store to register `XXX`; debugging detritus?
	(ds@set-format): Use `ds@macro`.
	(ds@set-format, let*lt-sign, LT, LO): Bracket unrecognized
	argument in single quotes.
	(ds@set-format): Characterize argument as "unrecognized", not
	"wrong".  Similarly with the fill style.
	(LI, LE, IND): Offer advice.
	(LE): Describe problem in same terms as `LI` ("no list active").
	(LC): Validate argument as numeric expression and die with
	diagnostic if it isn't one.
	(AL, ML, VL, BL, DL, RL, BVL): Weaken fatal diagnostic to
	warning; excess arguments are not a serious problem.
	(PS): Simplify control flow; since @error does not return,
	convert `ie` request to `if` and make `el` branch unconditional.
	(RP): Weaken fatal diagnostic to warning and return early;
	calling this macro without any references defined does no
	structural damage to a document.
	(INITI): Remove redundant conditional.

2023-01-16  G. Branden Robinson <g.branden.robinson@gmail.com>

	* m.tmac (IX): Delete.

2023-01-16  G. Branden Robinson <g.branden.robinson@gmail.com>

	* m.tmac (MC): Throw internal error if we don't leave
	`pg*cols-per-page` in a valid state after invalidating it to
	count columns.  Also simplify expression.

2023-01-16  G. Branden Robinson <g.branden.robinson@gmail.com>

	* m.tmac (1C): Warn and return early instead of bombing out if
	called when multiple columnation is inactive.  A no-op should
	not be a fatal error.

2023-01-16  G. Branden Robinson <g.branden.robinson@gmail.com>

	* m.tmac (@abort): Introduce macro for internal errors,
	unconditionally reporting a backtrace...
	(misc@pop-set, hd@split, MULN, df@print-float, IND): ..and use
	it instead of `@error` for problems with internal state.
	(IND): Also fix botch in reported error.

2023-01-16  G. Branden Robinson <g.branden.robinson@gmail.com>

	* m.tmac (SA): Reject an argument value > 1 as invalid.

2023-01-16  G. Branden Robinson <g.branden.robinson@gmail.com>

	* m.tmac (P): Quote unrecognized argument in warning diagnostic.
	(OK, PM): Refactor to use `\$0`.
	(1C): Clarify that formatting can go wrong if you suppress a
	page break when returning from multi- to single-column mode with
	a footnote pending.

2023-01-16  G. Branden Robinson <g.branden.robinson@gmail.com>

	* m.tmac (Tm): Align with definition of `Sm`, with analogous
	fallback definitions.

2023-01-16  G. Branden Robinson <g.branden.robinson@gmail.com>

	* m.tmac (Sm): Implement string for service mark, for DWB mm
	compatibility.
	* groff_mm.7.man: Document it.

2023-01-16  G. Branden Robinson <g.branden.robinson@gmail.com>

	* m.tmac (CS): Define to throw diagnostic when used without ".MT
	4".  (Later, if the "4.MT" file is sourced, this definition is
	replaced.)
	* groff_mm.7.man (Description): Clarify `CS` support status.

2023-01-16  G. Branden Robinson <g.branden.robinson@gmail.com>

	* m.tmac (MOVE, SM, AT, LO): Weaken diagnostics when given no
	arguments from (fatal) errors to warnings, then return.

2023-01-16  G. Branden Robinson <g.branden.robinson@gmail.com>

	* m.tmac (PIC): Bomb out (with diagnostic) if either of the
	width or height arguments are not numeric expressions.

2023-01-16  G. Branden Robinson <g.branden.robinson@gmail.com>

	* m.tmac (EPIC): Handle and shift off a leading "-L" argument
	before checking argument count.  Then, if fewer than two
	arguments remain, throw warning diagnostic and return early
	instead of bombing out.  Do bomb out (with diagnostic) if either
	of the width or height arguments are not numeric expressions.
	Fix bug which prevented third argument from being interpreted.
	Annotate potential future development.

2023-01-16  G. Branden Robinson <g.branden.robinson@gmail.com>

	* m.tmac (AU): Partially revert commit 4fd984adc9, 2021-07-17.
	`AU` can be called for the sole purpose of "closing" a document
	title "opened" with `TL`.
	* groff_mm.7.man (Macros) <AU>: Update description.

2023-01-16  G. Branden Robinson <g.branden.robinson@gmail.com>

	* m.tmac (TM): Warn if called without arguments.

2023-01-16  G. Branden Robinson <g.branden.robinson@gmail.com>

	* m.tmac (AST): Preserve any user-specified leading spaces in
	argument.

2023-01-06  G. Branden Robinson <g.branden.robinson@gmail.com>

	* m.tmac (P): Warn if argument is non-numeric, and discard it.
	Also warn if argument is out of range; people accustomed to
	setting the `Pt` register to 2 might mistakenly believe it to be
	meaningful here.

2023-01-03  G. Branden Robinson <g.branden.robinson@gmail.com>

	* mm/0.MT:
	* mm/5.MT: Drop never-read register `cov*mt0-ind`.

2023-01-03  G. Branden Robinson <g.branden.robinson@gmail.com>

	Improve cover sheet diagnostics.

	* m.tmac (MT): Warn and ignore if `COVER` or self already
	called.
	(COVER): Warn and ignore if `MT` already called.
	* mm/0.MT (cov@print-title): Abort if title not defined; tell
	user how to use the macros.
	(cov@print-authors): Add similar paranoid diagnostic that I
	don't think is reachable (since you _have_ to call `AU` to
	"close" `TL`).
	* mm/4.MT (cov@print-title, cov@print-authors):
	* mm/5.MT (cov@print-title): As "0.MT".

	* mm/4.MT: Get rid of spurious blank line in file.

2023-01-03  G. Branden Robinson <g.branden.robinson@gmail.com>

	Fix Savannah #63613.

	* mm/0.MT (cov*print-authors): Iterate through _all_ technical
	memorandum numbers instead of stopping one shy of the last.
	Problem appears to date back to introduction of TM support for
	memorandum type 1 in commit a48ab7b6d (groff 1.05, 1992-03-18).

	Fixes <https://savannah.gnu.org/bugs/?63613>.

2023-01-03  G. Branden Robinson <g.branden.robinson@gmail.com>

	Regression-test Savannah #63613.

	* tests/MT-1-reports-all-TM-numbers.sh: Do it.
	* mm.am (mm_TESTS): Run test.

2022-12-17  G. Branden Robinson <g.branden.robinson@gmail.com>

	* m.tmac (let*mt-sign): Check strings populated by optional
	arguments to `AU` macro for existence before interpolating them.

	Fixes <https://savannah.gnu.org/bugs/?24049>.  Thanks to Werner
	Lemberg for the report.

2022-11-22  G. Branden Robinson <g.branden.robinson@gmail.com>

	* mse.tmac: Set `pg*footer-size` to four vees, not four basic
	units; the latter is too small by orders of magnitude on
	typesetting output devices.

	Fixes <https://savannah.gnu.org/bugs/?63398>.  Thanks to Hans
	Bezemer for the report.

2022-11-21  G. Branden Robinson <g.branden.robinson@gmail.com>

	Regression-test Savannah #63398.

	* tests/mse_has-sufficient-footnote-space.sh: Do it.
	* mm.am (mm_TESTS): Run test.

2022-10-09  G. Branden Robinson <g.branden.robinson@gmail.com>

	[mm]: Add `--version` option support to mmroff.

	* mm.am (mmroff): Replace `@VERSION@` token in script.
	* mmroff.pl: Recognize `--version` option.
	* mmroff.1.man (Synopsis, Options): Document.

2022-10-09  G. Branden Robinson <g.branden.robinson@gmail.com>

	* mmroff.pl: Add proper diagnostic subroutine.  Add "progname"
	scalar to store the name of the program.
	(Die): New subroutine.
	(print_index, top level): Call Die() when encountering
	prohibitive problems instead of flinging a string into a void
	context.

2022-10-09  G. Branden Robinson <g.branden.robinson@gmail.com>

	* mmroff.pl: Enable Perl warnings.

2022-10-09  G. Branden Robinson <g.branden.robinson@gmail.com>

	[mm]: Refactor generation of "mmroff" script.

	* mmroff.pl: Replace absolute filespec with `@PERL@` replacement
	token.  This is documentary; the filespec was getting replaced
	anyway.
	* mm.am (mmroff): Use more idiomatic token replacement strategy.
	Also create target as a .tmp-suffixed file at first since it is
	not initially executable, so that we don't race against anything
	needing to run it in a parallelized build.  (This is a
	hypothetical concern; at present, nothing runs mmroff during the
	build.)

2022-10-02  G. Branden Robinson <g.branden.robinson@gmail.com>

	* m.tmac (pg@header): Add page length sufficiency check.

	Fixes <https://savannah.gnu.org/bugs/?24048>.  Thanks to Werner
	Lemberg for the report.

2022-10-02  G. Branden Robinson <g.branden.robinson@gmail.com>

	Regression-test Savannah #24048.

	* tests/short-pages-do-not-overflow-stack.sh: Test it.
	* mm.am (mm_TESTS): Run test.

2022-09-17  Nikita Ivanov <nikita.vyach.ivanov@gmail.com>

	* mm/ms.cov (cov@print-title, cov@print-authors): Escape
	newlines when beginning conditional blocks.

	Fixes <https://savannah.gnu.org/bugs/?63075>.  [Problems
	introduced by me in commits 59d1fd7a5e and 4fd984adc9, both
	2021-07-17. --GBR]

2022-09-16  Nikita Ivanov <nikita.vyach.ivanov@gmail.com>

	* m.tmac (misc@ev-keep): Select configured default font family,
	as with `.fam H` at the top of the document, for example, when
	switching to new environment.

	Fixes <https://savannah.gnu.org/bugs/?63067>.

2022-08-14  G. Branden Robinson <g.branden.robinson@gmail.com>

	* m.tmac (PY): Add new macro.
	(PE): Replace `init@reset` call with `PY` (and then space by
	half a vee as before).

	* groff_mm.7.man (PY): Document it.

	Fixes <https://savannah.gnu.org/bugs/?62900>.

2022-08-14  G. Branden Robinson <g.branden.robinson@gmail.com>

	* m.tmac (@warning, @error): Stop pointlessly using no-break
	control character when invoking the `tm` request, which never
	causes a break in formatted output.  (Management of the standard
	output and standard error streams is the user's responsibility.)
	(@error): Drop old-fashioned asterisk banners around error
	diagnostics.  Stop invoking `ab` with redundant and sometimes
	misleading arguments.  In groff 1.23, `ab` exits silently if
	given none.  We've already issued a diagnostic and moreover not
	all problems are with "syntax"; some are semantic.

2022-08-14  G. Branden Robinson <g.branden.robinson@gmail.com>

	* m.tmac (PS): Validate better; check for 2 arguments exactly.

2022-08-14  G. Branden Robinson <g.branden.robinson@gmail.com>

	* m.tmac (PS): Refactor; drop dead code.  The `pic*in` register
	was used only for dead stores; it was never read or tested.

2022-08-04  G. Branden Robinson <g.branden.robinson@gmail.com>

	* m.tmac (initialization): In nroff mode, surround automatically
	numbered footnote markers in body text with square brackets, as
	groff me(7) and ms(7) do.

2022-08-04  G. Branden Robinson <g.branden.robinson@gmail.com>

	* m.tmac (initialization): Recognize new register `V` for
	setting the vertical spacing from the command line, instead of
	blindly setting the vertical spacing two points larger than the
	type size.  Handle setting of `V` and type size `S` in case they
	are given with an appended scaling unit, using the same
	technique as groff ms(7)--if the values are over 1,000, assume
	that conversion to basic units by the formatter has already
	taken place.
	* groff_mm.7.man (Registers) <S, V>: Document it.

2022-08-03  G. Branden Robinson <g.branden.robinson@gmail.com>

	* m.tmac (:p): Define register as an alias of `ft*nr`; the
	former name is a documented DWB mm feature.

2022-08-01  G. Branden Robinson <g.branden.robinson@gmail.com>

	* groff_mm.7.man: Document more features.
	(Macros) <)E, VM>: Document these DWB mm internals as exposed by
	groff mm.
	(Macros) <B1, B2, MC>: Document as GNU extensions.
	(Strings) <BU, Ci, F>: Document.
	(Registers) <:R, Au, Ex, Fg, H8...H14, Oc, S>: Document.

2022-07-29  G. Branden Robinson <g.branden.robinson@gmail.com>

	* groff_mm.7.man: Document further differences between DWB mm
	and groff mm, including several unimplemented features.

2022-07-29  G. Branden Robinson <g.branden.robinson@gmail.com>

	* m.tmac: Remove pointless conditionals in initialization.
	Simplify if-else request pairs that did the same thing in both
	branches.

2022-07-28  G. Branden Robinson <g.branden.robinson@gmail.com>

	* groff_mm.7.man: Document `NE` macro.

2022-03-15  Damian McGuckin <damianm@esi.com.au>

	* m.tmac (eq@check): Compensate for display indentation when
	setting equation label.

	Fixes <https://savannah.gnu.org/bugs/?62190>.

2022-04-27  G. Branden Robinson <g.branden.robinson@gmail.com>

	Regression-test Savannah #62190.

	* tests/place-equation-labels-correctly-in-displays.sh: Test it.
	* mm.am (mm_TESTS): Run test.

2021-08-12  G. Branden Robinson <g.branden.robinson@gmail.com>

	* m.tmac (R): Alter to work analogously to `B` and `I` macros;
	accept multiple arguments if given, and alternate roman with
	previous font.  Stop explicitly turning off underlining.

2021-07-17  G. Branden Robinson <g.branden.robinson@gmail.com>

	Refactor author title handling.

	* m.tmac (AU): Initialize `cov*at!` array element to zero for
	current author number (`AT` already updates it).

	* mm/ms.cov (cov@print-authors): Enforce requirement documented
	in groff_mm(7) that .AU is mandatory if .COVER is used.  Emit
	diagnostic if `cov*au` is not defined, and skip remainder of
	macro definition.  Test for existence of authors' titles
	differently; now that `cov*at!` (a count of titles for the
	current author) is guaranteed to be initialized, we can use it
	as part of a while loop condition, instead of the hard-coded "9"
	as an arbitrary limit on the allowed quantity of author titles
	{though surely even that is obnoxiously high in practice}, and
	more importantly avoid using a \w escape to measure the width of
	the interpolation of a potentially undefined string.  Use `nop`
	to indent text output.  Delete apparent typo causing `mac`
	warning with respect to undefined `.` macro.  Introduce
	temporary strings for the author and author title "loop indices"
	to shorten and clarify logic.  Remove them when done.

	Fixes <https://savannah.gnu.org/bugs/?60926>.

2021-07-17  G. Branden Robinson <g.branden.robinson@gmail.com>

	* mm/ms.cov (cov@print-title): Enforce requirement documented in
	groff_mm(7) that .TL is mandatory if .COVER is used.  Emit
	diagnostic if `cov*title` is not defined, and skip remainder of
	macro definition.

2021-07-17  G. Branden Robinson <g.branden.robinson@gmail.com>

	* mm/ms.cov (COVEND): Fix thinko; test for existence of
	`cov*abs-arg` register with `r` conditional operator, not `d`.

2021-07-17  G. Branden Robinson <g.branden.robinson@gmail.com>

	* m.tmac: Stop emitting debugging diagnostic using undefined
	string.  Problem exposed by commit
	d6d98d2b3e0ad070037073bb288bbaee3fc04cf0, 8 December 2013.

	Fixes <https://savannah.gnu.org/bugs/?60397>.

2021-07-17  G. Branden Robinson <g.branden.robinson@gmail.com>

	Stop installing empty macro files.

	* mm.am: Delete variable `MMLOCALE`.
	(install_mm): Delete `for` loop that touches the files.
	(uninstall_mm): Delete `for` loop that deletes the files.
	* m.tmac: Update initializtion.
	  - Load the `\*[@country]_locale` file with `msoquiet` instead
	    of `mso`.
	  - Add version check to require groff 1.23 or later, since
	    the `msoquiet` request is now being used.
	  - Move "include guard" to follow the compatibility mode and
	    groff version checks.  Remove its `do` prefix.
	* groff_mm.7.man (Localization): Migrate topic into its own
	subsection and update discussion.

	Fixes <https://savannah.gnu.org/bugs/?60700>.

2021-07-17  G. Branden Robinson <g.branden.robinson@gmail.com>

	* mm/ms.cov (cov@print-firm): Do nothing if the `cov*firm`
	string is not defined.  Silences a `mac` warning and prevents
	the document date from being incorrectly aligned.

	* tests/ms_cover_sheet_robust_to_missing_AF.sh: Test it.
	* mm.am (mm_TESTS): Run test.

	Fixes <https://savannah.gnu.org/bugs/?60915>.

2021-07-14  G. Branden Robinson <g.branden.robinson@gmail.com>

	* m.tmac: Rename `cov*mt-addresse` to `cov*mt-addressee`.
	* NOTES: Update the only place the foregoing is documented.

2021-05-31  G. Branden Robinson <g.branden.robinson@gmail.com>

	* groff_mm.7.man (Description/Macros) <LT>: Document the "SP"
	{simplified} letter style more completely.  Salutations and
	formal closings are omitted.

	Solves the remaining part of bug #60373, "the formal closing is
	omitted completely".  And, regarding the salutation, #60390.

	Fixes <https://savannah.gnu.org/bugs/?60373> and
	<https://savannah.gnu.org/bugs/index.php?60390>.

2021-05-30  Bjarni Ingi Gislason <bjarniig@rhi.hi.is>

	* m.tmac (let@sg_SP): Stop placing a comma after the first
	argument (an author name set by AU) if the second argument is
	empty (an author title set by AT).

	Solves another part of bug #60373, "the writer's name at the
	bottom is followed by a trailing comma".

	Fixes <https://savannah.gnu.org/bugs/?60389>.

2021-05-30  Bjarni Ingi Gislason <bjarniig@rhi.hi.is>

	* m.tmac (let@print-head): Quote the interpolation of the string
	`let*lo-SJ`.

	Solves part of bug #60373, "[t]he subject line shows only the
	first word".

	Fixes <https://savannah.gnu.org/bugs/?60388>.

2021-05-30  G. Branden Robinson <g.branden.robinson@gmail.com>

	Add regression tests for Savannah #60373.

	* tests/LT_SP_AU_without_AT_works.sh:
	* tests/LT_SP_multi-word_LO_SJ_works.sh: Add tests.
	* mm.am (mm_TESTS): Run tests.

2021-05-30  Tadziu Hoffman <hoffmann@usm.uni-muenchen.de>

	Fix Savannah #57034.

	* m.tmac (AT): Count author title declarations.
	(let*mt-sign): Use correct index when iterating author names.
	Prevent page break between author names and titles.  Iterate
	author titles and write them.

	Fixes <https://savannah.gnu.org/bugs/?57034>.

2021-05-30  G. Branden Robinson <g.branden.robinson@gmail.com>

	Add regression test for Savannah #57034.

	* tests/MT_5_includes_AT_in_SG.sh: Test it.  Thanks to Ken
	Mandelberg for the reproducer.
	* mm.am (mm_TESTS): Add variable storing script name.
	(TESTS): Append `mm_TESTS` to run it.
	(EXTRA_DIST):  Append `mm_TESTS` to ship it.

2021-05-30  Bjarni Ingi Gislason <bjarniig@rhi.hi.is>

	* mm/5.MT (cov@print-title): Fix missing diagnostic.  Memorandum
	type 5 now requires a title to be declared with .TL.

	Fixes <https://savannah.gnu.org/bugs/?59563>.

2021-05-30  G. Branden Robinson <g.branden.robinson@gmail.com>

	[mm]: Cease warning level manipulation.

	Stop mm macro package from manipulating warnings.

	* m.tmac: Remove code that attempted to enable all warnings if
	none were given on the command line.  It did this by simply
	comparing the value of the warning register (\n[.warn]) against
	the default value; but of course, a user could specify -w
	options that exactly matched the default and the test would not
	be able to tell, causing puzzling and undesired behavior.
	Furthermore, the hard-coded default was out of date and did not
	correspond to recent releases of groff.  If you want all
	warnings on, use the ".warn" request with no arguments in your
	mm document or pass "-w w" to groff (see troff(1) or the Texinfo
	manual for more on warnings).

	See commit 5aa934e7, 20 February 2020.

2021-05-30  G. Branden Robinson <g.branden.robinson@gmail.com>

	* examples/letter.mm: Revise to be a better example: use macro

	* Added number variable Hss

	* added hd*h1-text to be used in user defined macro TP.
	* -U needed for SETR (I really need 'mv', 'echo', 'rm'
	  and 'test' builtin!)
	* Rewritten the reference system, SETR now prints to stderr
	  if the number register Qrf > 0. Store in the filename
	  that is the argument to .INITR

Fri Sep 6 07:13:07 1996 Jörgen Hägg (jh at axis.se)

	* version 1.30
	* This is more like a beta-release, bugs might pop up. :-)
	* last line in TOC was not correctly terminated (missing .br)
	* changed the indentation for displays, it will now
	  indent to the current indent, not the one at the definition
	  of the display.
	* Equation marks should now work better, indentation also.
	* included these bug fixes from Larry Jones:
	*   The documentation for the argument to .AS was incorrect for MT 4.
	*   \*(EM should be a double-dash for nroff.
	*   \nS is in points, not units.
	*   If \nO isn't set, the default page offset should be .75i for nroff
		and .963i for troff.
	*   .S D should set the point size to \nS, not 10.
	*   .S was setting the vertical spacing based on the old point size
		instead of the new point size.
	*   Got rid of a spurrious .br that prevented run-in headings from
		working.
	*   Reset the .SP counters in pg@header so that spacing on one page
		won't affect spacing on subsequent pages.
	*   Allow .AU and .AF with no arguments (real mm does, even though it
		isn't documented).
	*   Do .init@reset first thing to initialize the default environment.
	*   For MT 4, the title should be 4 points larger than the default size,
		not 12 point.
	*   The cover environment needs to be initialized.
	*   Printing the abstract on the first page needs to be controlled by
		the .AS argument.
	*   Heading eject should be suppressed if the heading immediately
		follows the first page stuff (title, author, etc.).
	*   support for table of contents numbering style (.nr Oc)
	*   changes the troff empty line height from .25v to .5v
	*   fixed section page numbering
	*   fixed a really nasty bug in footnotes that could cause you
		to lose the page footer completely if the very first
		footnote on the page occurred at just the wrong place
