	Fix ms .TC macro by allowing it to actually use lowercase Roman
	numerals for the page(s) of the table of contents when a custom
	title (header or footer) is defined containing '%'.

	As a side effect, eliminate the PN register, which was
	apparently misused because it was undocumented and had a name
	just long enough to be both suggestive and ambiguous.  Another
	pin goes into my Ken Thompson voodoo doll.

	* tmac/s.tmac (IX): Write out page number of index term(s) in
	using the % register (instead of PN), obtaining whatever format
	is assigned to the register at that time.
	(CH): Similarly, output %, not PN, in the center of the default
	heading.
	(PT): Save the format of %, set it to decimal, copy its value to
	a new register, pg*page-number-in-decimal, then restore %'s
	previous format.  Compare the new register, not %, to 1 to
	determine whether special page one behavior should be used.
	(pg*end-page): Assign pg*next-format to %, not PN.
	(XA): Define toc*num with the interpolation of %, not PN.

	* tmac/tests/s-TC-works-with-percent-in-custom-titles.sh: Test.
	* tmac/tmac.an (tmac_TEST): Run test.

	Problem appears to be very old; as I read it, Larry Kollar was
	complaining of it in his ms.ms document over 20 years ago.

	Fixes <https://savannah.gnu.org/bugs/?59345>.

2020-10-25  G. Branden Robinson <g.branden.robinson@gmail.com>

	* man/groff.7 (Requests/Request short reference) <.af>: Fix
	error; "l" is not a valid register format.  Explain what the
	request does, and the default format, as tersely as possible.

2020-10-22  G. Branden Robinson <g.branden.robinson@gmail.com>

	Use only malloc() and free() to manage memory of paths opened by
	the parser instead of mixing in C++ new/delete management under
	some runtime-dependent circumstances.

	* src/libs/libgroff/relocate.cpp (relocatep): Use malloc(), not
	new.
	* src/roff/troff/input.cpp (process_macro_file,
	process_startup_file, macro_source): Use free(), not (a_)delete.

	Thanks to an anonymous contributor for the report and patch.

	Fixes <https://savannah.gnu.org/bugs/index.php?56694>.

2020-10-22  G. Branden Robinson <g.branden.robinson@gmail.com>

	* man/groff_char.7.man (Description/Special character escape
	forms): Clarify discussion of Unicode Normalization Form D and
	its applicability to code points acceptable in Unicode numeric
	special character escapes.  Also document that these escapes
	must use uppercase hexadecimal digits.

	Attempts once again to slay the unkillable beast that is
	<https://savannah.gnu.org/bugs/index.php?57618>.

2020-10-21  Ingo Schwarze <schwarze@openbsd.org>

	On systems without NAME_MAX, use FILENAME_MAX as a last resort.

	Problem reported by Eli Zaretskii <eliz at gnu dot org>
	on MS Windows in https://savannah.gnu.org/bugs/?55449

2020-10-20  G. Branden Robinson <g.branden.robinson@gmail.com>

	* src/roff/troff/env.cpp (environment::possibly_break_line):
	Emit break warning and return if the output width is not
	positive.  The code assumes that it will be and loops infinitely
	if it isn't.  I _think_ this is because we're not able to get
	width data for (some?) CJK glyphs.  Based on a patch by Osamu
	Sayama.

	* src/roff/groff/tests/\
	do_not_loop_infinitely_when_breaking_cjk.sh: Test it.
	* src/roff/groff/groff.am: Run test.

	Fixes <https://savannah.gnu.org/bugs/index.php?44018>.

2020-10-20  G. Branden Robinson <g.branden.robinson@gmail.com>

	* src/preproc/tbl/table.cpp (table::init_output): Save the value
	of \n[.tabs] when starting a table.  In the reset macro, restore
	the saved value.

	Based on a patch by Bjarni Ingi Gislason (tweaked to use a more
	normative preprocessor symbol; "REG"s aren't "NAME"s).

	* src/preproc/tbl/tests/save-and-restore-tab-stops.sh: Test it.
	* src/preproc/tbl/tbl.am (tbl_TESTS): Run test.

	Fixes <https://savannah.gnu.org/bugs/index.php?42978>.

2020-10-20  G. Branden Robinson <g.branden.robinson@gmail.com>

	* src/roff/nroff/nroff.sh: Recognize -E option and pass it
	through to troff.  Document it in usage message.
	* src/roff/nroff/nroff.1.man: Document new -E option.

	Based on a patch by Ingo Schwarze.

	Fixes <https://savannah.gnu.org/bugs/index.php?44289>.

2020-10-18  G. Branden Robinson <g.branden.robinson@gmail.com>

	* tmac/an-old.tmac: Stop remapping ` and '.  Our own pages now
	appear to be clear of wrong-quote problems, so let's make them
	visible if they recur.  Those who don't want to fix bad man
	pages (distributors, site admins) can restore the mappings in
	their man.local files.

2020-10-18  G. Branden Robinson <g.branden.robinson@gmail.com>

	* tmac/an-old.tmac (an-warn): New; emits warning diagnostic.
	(R): Use new macro instead of .tm* requests directly.

2020-10-18  Ingo Schwarze <schwarze@openbsd.org>

	#include "config.h" before <stdio.h>

	Required with e.g. gcc 4.2.1 because gnulib/lib/stdio.in.h
	uses the "restrict" keyword since this gnulib commit:
	commit 182afcba2635cbff91240656c7fb3742dd23ab6f
	Author: Bruno Haible <bruno@clisp.org>
	Date: Sat Feb 22 20:57:30 2020 +0100

	Otherwise, the build may die from the declaration of
	various printf-like functions with messages like:
	./lib/stdio.h:851: error: expected ',' or '...' before 'fp'

	* src/libs/libgroff/assert.cpp, src/libs/libgroff/errarg.cpp,
	src/libs/libgroff/error.cpp, src/preproc/eqn/eqn.ypp:
	#include "config.h".

2020-10-18  Bertrand Garrigues <bertrand.garrigues@laposte.net>

	hpftodit: incorrect 'delete' after new[]

	* src/utils/hpftodit/hpftodit.cpp (output_font_name): use
	'delete[]'.

	Fixes bug #55331. Found by David Binderman, fixed by Ingo
	Schwarze.

2020-10-18  Bertrand Garrigues <bertrand.garrigues@laposte.net>

	preconv: don't use libuchardet if input is stdin

	* src/preproc/preconv/preconv.cpp (do_file): don't call
	detect_file_encoding if input file is "-"

	This fixes the failure on MS-Windows described #55334, however
	this does not fix the encoding detection with uchardet if the
	input is stdin (the user would have to pass with -D the correct
	encoding as explained in the man page).

2020-10-17  G. Branden Robinson <g.branden.robinson@gmail.com>

	* src/preproc/eqn/lex.cpp (troff_defs): Set the "..." token on
	the baseline, not vertically centered, aligning the actual
	behavior with what our eqn(1) man page has claimed since 2007.

	Fixes <https://savannah.gnu.org/bugs/index.php?59285>.

2020-10-17  G. Branden Robinson <g.branden.robinson@gmail.com>

	* src/devices/grops/grops.1.man
	(Usage/TrueType and other font formats): Remove dead URL to
	ttftot42 utility.  Update URL to fontforge tool.  Replace much
	of the discussion with an example, motivated by Jordan Torbiak's
	"groff-install-font" script on GitHub Gist, of how to add the
	Roboto Slab Regular font to a user-local groff font directory
	{and how to test it, too}.

	Fixes <https://savannah.gnu.org/bugs/index.php?58077>.

2020-10-17  G. Branden Robinson <g.branden.robinson@gmail.com>

	* src/utils/afmtodit/afmtodit.pl: Report program name in warning
	diagnostics.

	Continues the long process of fixing Savannah #52463.

2020-10-16  G. Branden Robinson <g.branden.robinson@gmail.com>

	* src/preproc/eqn/main.cpp (main):
	* src/preproc/pic/main.cpp (main):
	* src/preproc/tbl/main.cpp (main):
	* tmac/eqnrc:
	* tmac/troffrc: Perform checks of register and macro definitions
	with a .do request, since we might be in compatibilty mode.

2020-10-16  G. Branden Robinson <g.branden.robinson@gmail.com>

	* src/roff/troff/input.cpp (do_if_request): Emit warning of type
	"syntax" if a groff conditional expression extension is used
	when compatibility mode is active.

	* doc/groff.texi:
	* src/roff/troff/troff.1.man: Update description of "syntax"
	warning type to be more general.  It was inaccurate, referring
	only to "dubious syntax in numeric expressions", which was not
	the case.  Instead it was being used only for poor construction
	of character classes with the .class request.

2020-10-14  Ingo Schwarze <schwarze@openbsd.org>

	In groff(1), fix the combination of -v with -k, -j, and -J.

	* src/roff/groff/groff.cpp: Pass the -v option through to the
	preconv, chem, and ideal preprocessors, just like for all
	other preprocessors, to print the version of the preprocessor
	and to avoid garbage output.

	Bugfix patch from Eli Zaretskii <eliz at gnu dot org>
	submitted in: https://savannah.gnu.org/bugs/?55297

2020-10-12  Bertrand Garrigues <bertrand.garrigues@laposte.net>

	Update 'gnulib' submodule.

	* gnulib: now points on d60a35e94c4f5b8f09f15828242418f5073d46e7
	from 'gnulib' repository.

	* configure.ac: minimum autoconf version is now 2.64 due to
	gnulib upgrade.

	* FOR-RELEASE: add the gnulib update to the checklist.

2020-10-11  G. Branden Robinson <g.branden.robinson@gmail.com>

	* tmac/andoc.tmac: When switching between macro packages in
	andoc and using continuous-rendering mode, flush any partially
	collected output line and write page footer.
	(reload-doc): Call an-end if it is defined.
	(reload-man): Call doc-end-macro if it is defined.
	* tmac/tests/andoc-flush-between-packages.sh: Add regression
	test.
	* tmac/tmac.am (tmac_TESTS): Run test.

	Fixes <https://savannah.gnu.org/bugs/index.php?59106>.

2020-10-11  G. Branden Robinson <g.branden.robinson@gmail.com>

	* tmac/andoc.tmac: Remove traps set by mdoc package by the names
	they actually use.
	* tmac/tests/andoc-clear-doc-traps.sh: Add regression test.
	* tmac/tmac.am (tmac_TESTS): Run test.

	Fixes <https://savannah.gnu.org/bugs/index.php?59246>.

2020-10-10  G. Branden Robinson <g.branden.robinson@gmail.com>

	* src/preproc/tbl/table.cpp (table::init_output): In the release
	macro written to the output, reword the warning diagnostic that
	is emitted when a table row is to be output without enough room
	before the next page location trap.  The former wording said
	that a "text block" would not fit on the page, and that is
	normally how table rows grow longer than one line in the first
	place.  However, there are other ways the conditional can be
	satisfied, as witnessed in Savannah #57665, so simply say what
	is known; that the table _row_ overruns the space to the next
	trap (we say the row won't "fit on [the] page").

	Fixes <https://savannah.gnu.org/bugs/index.php?59233>.

2020-10-10  G. Branden Robinson <g.branden.robinson@gmail.com>

	* src/preproc/tbl/table.cpp
	(double_line_entry::double_line_entry):
	(double_line_entry::simple_print): Remove garbage lines
	inadvertently added in previous commit.

2020-10-09  G. Branden Robinson <g.branden.robinson@gmail.com>

	Stop tbl from injecting spurious blank lines (and emitting
	spurious warnings about tables and "text blocks" not "fitting on
	a page") into long tables in man pages when continuous rendering
	is used (the default for nroff output devices).

	* src/preproc/tbl/table.cpp (USE_KEEPS_REG): New preprocessor
	symbol stores name of groff register for dynamic determination
	of keep usage.
	(table::init_output): If the NOKEEP flag is not set, then in
	generated groff output, see if the usekeeps register is defined;
	if not, define it and enable usage of keeps.
	(table::do_row): In groff output, check usekeeps register before
	calling keep and release macros.
	(table::do_bottom): In groff output, check usekeeps register
	before calling release macro.

	* tmac/an-old.tmac (TS): Set the usekeeps register used by tbl
	to the logical complement of the man(7) cR (continuous
	rendering) register.

	* tmac/tests/an-old_TS_do_not_keep_tables_when_cR_set.sh: Add
	regression test.
	* tmac/tmac.am (tmac_TESTS): Run test.

	Problem appears to date back to the introduction of continuous
	rendering in groff 1.17 (3 May 2001).

	Fixes <https://savannah.gnu.org/bugs/index.php?57665>.

2020-10-09  G. Branden Robinson <g.branden.robinson@gmail.com>

	* src/preproc/tbl/table.cpp (simple_entry::position_vertically):
	(block_entry::position_vertically):
	(table::determine_row_type):
	(printfs): Update assertions to indicate what actually went
	wrong.

2020-10-02  G. Branden Robinson <g.branden.robinson@gmail.com>

	* src/roff/troff/node.cpp: Make diagnostics slightly more
	informative in unusual error cases.
	(real_output_file::~real_output_file): If ferror() reports error
	status on a stream say that, instead of "error writing".  If it
	does not, but fflush() fails on the stream, describe the flush
	as failing, and use strerror() since fflush() sets errno.  If
	pclose() fails, say that we were unable to close a pipe instead
	of repeating the name of the C library function to the user, who
	might not be a C programmer.  Report sterror() in this case and
	for a failing fclose().
	(real_output_file::flush): Repeat updated fflush() logic from
	previous function.

2020-09-30  G. Branden Robinson <g.branden.robinson@gmail.com>

	* tmac/an-old.tmac (register setup): Make interaction of \n[C]
	register and HTML output more clear in code and comments.

2020-09-30  G. Branden Robinson <g.branden.robinson@gmail.com>

	* src/roff/groff/tests/regression_savannah_59202.sh: Reduce test
	case.

2020-09-29  G. Branden Robinson <g.branden.robinson@gmail.com>

	Fix SEGV arising from recursing destructor.

	* src/roff/troff/node.h (output_file): Add class member
	`is_dying` to track whether destructor has already been entered;
	initialize false.
	* src/roff/troff/node.cpp (real_output_file::~real_output_file):
	Set `is_dying` true when destructor entered.
	* src/roff/troff/div.cpp (cleanup_and_exit): Only delete
	`the_output` object if it is not already being destroyed.
	* src/roff/groff/tests/regression_savannah_59202.sh: Add test.
	* src/roff/groff/groff.am (groff_TESTS): Run test.

	Thanks to "hackerb9" for reporting the problem.  Problem appears
	to date back to groff 1.02 (June 1991) or earlier.

	Fixes <https://savannah.gnu.org/bugs/index.php?59202>.

2020-09-28  G. Branden Robinson <g.branden.robinson@gmail.com>

	* tmac/an-old.tmac (register setup): Condition decisions on
	\n[an-html] rather than a string comparison using \*[.T]; that
	is what the register is there for.

2020-09-28  G. Branden Robinson <g.branden.robinson@gmail.com>

	* tmac/andoc.tmac: Save alias to .ne request.
	(reload-doc): Restore .ne request, which an-old.tmac meddles
	with if continuous rendering is used.  (The meddling ultimately
	dates back to 777e2d262862621966c18d685a000cc88f432bc6, 26
	January 2002, which simply redefined .ne as empty on nroff
	devices.)

2020-09-27  G. Branden Robinson <g.branden.robinson@gmail.com>

	Ship tests in distribution archive.

	* src/preproc/preconv/preconv.am (EXTRA_DIST):
	* src/roff/groff/groff.am (EXTRA_DIST):
	* src/roff/nroff/nroff.am (EXTRA_DIST):
	* tmac/tmac.am (EXTRA_DIST): Add
	$({preconv,groff,nroff,tmac}_TESTS), as appropriate.

	* src/roff/nroff/nroff.am (MOSTLYCLEANFILES): Stop adding
	$(nroff_TESTS), which can only have unhappy consequences.

2020-09-27  G. Branden Robinson <g.branden.robinson@gmail.com>

	* tmac/tmac.am: Fix problem with recently-relocated mdoc macro
	files not ending up in the right place in the distribution
	archive.
	(dist_tmac_DATA): Also include $(TMACUNSTRIPFILES).
	(TMACMDOCSTRIPFILES): Rename from $(TMACMDOCFILES).  Update
	interpolation sites.
	(TMACMDOCUNSTRIPFILES): New variable holds mdoc macro files in
	the tmac/mdoc subdirectory.  Stop adding these files to
	$(TMACUNSTRIPFILES) since those reside in tmac/ directly.
	(EXTRA_DIST): Add $(TMACMDOCUNSTRIPFILES).
	($(TMACSTRIPFILES)): Depend only on $(TMACUNSTRIPFILES).
	($(TMACMDOCSTRIPFILES)): Add new rule, much like the foregoing.
	Depend on $(TMACMDOCUNSTRIPFILES) and copy files into tmac/mdoc.
	(dist-hook, tmac-dist-hook): Remove; they no longer do any
	distinct work.

	Fixes <https://savannah.gnu.org/bugs/index.php?59186>.

2020-09-26  G. Branden Robinson <g.branden.robinson@gmail.com>

	* src/preproc/tbl/table.cpp (table::init_output):
	(table::compute_expand_width):
	(table::compute_separation_factor): Use consistent format for
	diagnostic messages.
	+ Do not spread a single diagnostic across multiple lines.
	+ Report messages in GNU Coding Standards format, that is:
	+ Report the name of the file the problem is in...
	+ ...then the line number...
	+ ...then the diagnostic severity level...
	+ ...then the specific problem.

2020-09-26  G. Branden Robinson <g.branden.robinson@gmail.com>

	* tmac/an-old.tmac: Emit warnings when configuration registers
	are ignored when producing output for HTML.

2020-09-25  G. Branden Robinson <g.branden.robinson@gmail.com>

	* tmac/an-old.tmac (an-p-footer): Define \*[an-page-string] if
	(1) the output device is not HTML; (2) \n[X] has been defined;
	and (3) the page number has not yet reached the threshold
	defined by \n[X].

	Fixes <https://savannah.gnu.org/bugs/index.php?59179>.

2020-09-25  G. Branden Robinson <g.branden.robinson@gmail.com>

	Add regression test for Savannah #59179.

	* tmac/tests/an-old_X_register_works.sh: Do it.
	* tmac/tmac.am (tmac_TESTS): Run it.

2020-09-25  G. Branden Robinson <g.branden.robinson@gmail.com>

	* tmac/an-old.tmac:
	* tmac/doc.tmac-u: Emit more informative fatal diagnostic when
	installed version of groff is too old.  Report the version found
	and explicitly note consequent abort.

2020-09-25  G. Branden Robinson <g.branden.robinson@gmail.com>

	* tmac/tmac.am: Regenerate stripped macro files upon changes to
	any of their unstripped counterparts.  This is crude, but they
	weren't being regenerated at _all_.  Defeating a central
	function of Make is bad.
	(TMACUNSTRIPFILES): New variable.  Populate with -u files.
	($(TMACMDOCFILES) $(TMACSTRIPFILES)): Depend on
	$(TMACUNSTRIPFILES).

2020-09-25  G. Branden Robinson <g.branden.robinson@gmail.com>

	* tmac/an-old.tmac:
	* tmac/andoc.tmac:
	* tmac/doc.tmac-u:
	* tmac/s.tmac: Clarify fatal diagnostics by informing the user
	that the program is aborting.

2020-09-25  G. Branden Robinson <g.branden.robinson@gmail.com>

	* tmac/www.tmac.in: Revise diagnostic message handling.
	(www:fatal): New macro handles fatal macro usage errors.
	(www:lenstr): Use www:fatal instead of writing to standard error
	with .tm (rather than www:error) and then calling .ab without
	arguments, which produces an unsightly "User Abort." message.
	(www:lenstr):
	(www:splitstr):
	(www:url_breaks):
	(www:url_breaks_split):
	(LINKSTYLE): Report expected number of arguments in diagnostics.
	(www:fontstyle): Shorten diagnostic message.

2020-09-25  G. Branden Robinson <g.branden.robinson@gmail.com>

	* src/roff/troff/div.cpp
	(top_level_diversion::clear_diversion_trap): Fix copy and paste
	error in diagnostic, which wrongly reported that a top-level
	diversion trap couldn't be "set" when "clear"ed was meant.

2020-09-19  G. Branden Robinson <g.branden.robinson@gmail.com>

	* src/preproc/grn/main.cpp (conv):
	* src/roff/troff/node.cpp (suppress_node::tprint): Remove
	embedded newlines from diagnostic messages.

2020-09-18  G. Branden Robinson <g.branden.robinson@gmail.com>

	* tmac/an-old.tmac: Move setup of remaining rendering option
	parameters (registers C, D, P, and X) to end of file.

2020-09-17  G. Branden Robinson <g.branden.robinson@gmail.com>

	* tmac/an-old.tmac (TH): Move setup of rendering parameter
	registers IN and SN from here to the end of the file.  Update
	comments.

2020-09-17  G. Branden Robinson <g.branden.robinson@gmail.com>

	* tmac/an-old.tmac: Drop \*[an-empty] string.  This string is
	documented as preventing "looping" (presumably infinitely) if
	someone calls a two-font macro with an inconvenient parameter;
	the example shown is ".RB ( \\ )".  This string was being
	interpolated at the end of each argument pair to the two-font
	macros BI, BR, IB, RB, and RI.  This code dates back to groff
	1.10 (dc5351364982f78f8c630f1e856d692d4a82666f, 26 November
	1995).  Did you notice a two-font macro missing?  It was: IR.
	Using it with the proscribed input fails to cause a problem; the
	others similarly operate just fine when the empty string
	interpolation is removed.  Presumably at some point in the past
	25 years, this workaround became unnecessary.
	(BI, BR, IB, RB, RI): Remove interpolations of string.

	* tmac/tests/an-old_avoid_two-font_denial_of_service.sh: Add
	regression test.
	* tmac/tmac.am (tmac_TESTS): Run test.

2020-09-16  G. Branden Robinson <g.branden.robinson@gmail.com>

	* tmac/an-old.tmac: Refactor continuous rendering handling.
	Relocate set up of \n[cR] to end of file in parallel with other
	rendering parameter management.  Instead of conditionally
	defining the an-ne and an-bp macros, define them
	unconditionally.  Also define them with .de instead of .de1,
	since they will only be called within the contexts of macros
	that are already running with compatibility mode off (i.e., the
	public interface macros).  Relocate definition of an-end to sit
	alongside these other continuous-rendering-mode specific macros
	and avoid a forward reference and scattering of \n[cR]
	conditionals around the file.
	(an-set-up-continuous-rendering): Define new macro to move
	macros (and end macro) into place.  Call it at the end of the
	file only if cR eventually winds up being true.

2020-09-16  G. Branden Robinson <g.branden.robinson@gmail.com>

	* tmac/an-old.tmac: Improve name space management.  Rename .ne
	request to .an-ne instead of outright clobbering it (and in

	* tmac/an-old.tmac: Drop .ll hack for LL register.

	Drop the .ll hack for setting the line length on nroff devices.

	Once upon a time, the only way to get man pages to render on a
	terminal at any width other than the nroff default of 65n was to
	put an .ll request into the page--a mortal sin against
	portability--or your man(1) program could sneak such a request
	into nroff's input stream.

	Also, long ago, John Eaton of UT Austin wrote a man(1) program.
	In a few years this implementation branched into two lines of
	development, which I'll call man-db man (Wilford/Polacco/Watson)
	and another, Brouwer/Lucifredi man, which as of this writing saw
	its last release in 2011 (1.6g).

	The man and mdoc macros of groff 1.18 (July 2002) introduced an
	LL register to configure the line length, respecting an -rLL
	command-line option.  The source change was made by Werner
	Lemberg on 3 May 2002 and Colin Watson updated man-db man(1)--on
	the same day!--to synthesize the option when calling groff.

	Later, in August 2005, Keith Marshall, a user of vesion 1.5m of
	Brouwer/Lucifredi man(1), which did not set the LL register,
	suggested that the existing .ll setting (technically, the value
	of \n[.l], the only way the result of an .ll request could be
	introspected) be honored in the absence of the LL register.
	However, it is impossible to distinguish a user-supplied ".ll
	65n" request from nroff's default setting, which was in that
	case overridden to the modern default of 78n.

	And so, in what is now git commit
	f9d5df4aebd3d834b4084ffefa52a115e00dce38 (1 September 2005), it
	was done.

	This led to (1) surprising behavior for users accustomed to old
	methods and desirous of the nroff default and (2) lengthy
	apologia in groff source code comments and the groff_man(7) man
	page.

	Ironically, Brouwer/Lucifredi man(1) had already added support
	for the LL register by the time of its 1.6 release two months
	earlier (20 June 2005).  (Curiously, it did so similarly to the
	old .ll hack, by injecting an '.nr LL' request into groff's
	input stream, rather than using the -r command-line option.)
	Moreover, Marshall and the groff list were already aware of
	this, but the change was accepted anyway because version 1.6
	was "too new"!  (Distributions are slow sometimes, true...)

	Let us survey the field in 2020.  man-db man(1) has supported
	the LL register for eighteen years, and Brouwer/Lucifredi man(1)
	for fifteen.  Heirloom Doctools's man macros set the line length
	to 78n on nroff devices unconditionally.  mandoc(1) similarly
	also always formats for 78 columns on terminals.  groff's
	mdoc(7) macros grew support for LL in parallel with man(7) in
	2002 and never added the \n[.l] introspection at all.

	There no longer seems to be any reason to preserve this hack.

	* tmac/an-old.tmac (initialization): Drop complex setup of LL
	register.
	(TH): Relocate line length reset; no behavior change.
	(after .mso man.local): Initialize LL only if the user hasn't;
	use device default in troff mode, and 78n in nroff mode.

	* tmac/groff_man.7.man.in (Options) <-rLL>: Stop documenting .ll
	hack.

	Migrate macro packages from font CW to CR.  The font name "CW"

	Update documentation of .ss request.

	* doc/groff.texi (Manipulating Filling and Adjusting): Rewrite
	documentation of .ss request and \n[.ss] and \n[.sss] escapes.
	Note that negative values are not permitted in either argument
	to .ss.  Use new terminology, "minimal inter-word spacing" and
	"additional inter-sentence spacing" for clarity.  Clarify that
	additional inter-sentence spacing is only used when the output
	line is not full when the end of a sentence occurs.  Add index
	nodes to help readers find discussion of details of spacing
	between words and sentences.  Move discussion of differences
	from AT&T troff to section "Implementation Differences".  Update
	example to more closely resemble a real-world case, use second
	argument to .ss request, and eliminate hackish use of .nop
	request.

	* man/groff_diff.7.man (New number registers): Recast in
	parallel with the foregoing.

	* man/groff.7.man (Read-only registers): Use new terminology and
	describe \n[.ss] and \n[.sss] in meaningful terms, not by
	reference to arguments to the .ss request (which wasn't even
	accurate, because these registers have default values).

	Fixes https://savannah.gnu.org/bugs/index.php?54101.

	(detect_file_encoding): Alter debugging output so it's easier to
	grep and verify Emacs coding tag detection.

	* src/preproc/preconv/preconv.1.man (Bugs): Delete; its sole
	concern was the absence of this feature.
	(Usage): Document detection algorithm in more detail.  Note
	which detection methods don't work on unseekable input (pipes).
	Offer recommendations for those struggling with encoding
	detection.
	(Usage/Coding Tags): Stop manipulating line adjustment.  Use
	hyphen-minus (\- escape) characters in coding tag names, since
	they are literals that one might copy and paste.  Stop
	referencing XEmacs, whose development appears moribund.
	(See Also): Add cross-references to iconv(3) and locale(7) man

	* **/*.{man,tmac}: Save compatibility mode robustly.

	Use new \n[.cp] register to save compatibilty mode.

	Use register names based on the filename (at the source
	maintenance level) to avoid clobbering other files' saved
	compatibility modes.

	* tmac/html.tmac: Eliminate test of saved-compatibility

2020-04-16  G. Branden Robinson <g.branden.robinson@gmail.com>

	Implement new read-only .cp register.

	Within a .do request, \n[.cp] holds the saved value of
	compatibility mode.

	The register \n[.cp] is specialized and may require a statement
	of rationale.  When writing macro packages or documents that use
	groff features and which may be mixed with other packages or
	documents that do not—common scenarios include serial processing
	of man pages or use of the .so or .mso requests—you may desire
	correct operation regardless of compatibility mode in the
	surrounding context.  It may occur to you to save the existing
	value of \n(.C into a register, say, _C, at the beginning of
	your file, turn compatibility mode off with “.cp 0”, then
	restore it from that register at the end with “.cp \n(_C”.  At
	the same time, a modular design of a document or macro package
	may lead you to multiple layers of inclusion.  You cannot use
	the same register name everywhere or you risk “clobbering” the
	value from a preceding or enclosing context.  The two‐character
	register namespace of AT&T troff is confining and mnemonically
	challenging; you may wish to use groff's more capacious
	namespace.  However, attempting “.nr _my_saved_C \n(.C” will not
	work in compatibility mode; the register name is too long.
	“This is exactly what .do is for,” you think, “.do nr
	_my_saved_C \n(.C”.  The foregoing will always save zero to your
	register, because .do turns compatibility mode off while it
	interprets its argument list.  What you need is:
		.do nr _my_saved_C \n[.cp]
		.cp 0
	at the beginning of your file, followed by
		.cp _my_saved_C
	at the end.  As in the C language, we all have to share one big
	namespace, so choose a register name that is unlikely to collide
	with other uses.

	It's too easy for the nroff version to get desynced from the
	groff version when we're running test cases, leading to spurious
	results.  Make it easier to see a discrepancy.

	* src/roff/nroff/nroff.sh: Call groff with -v or --version when
	we are called that way.  Let test cases tell us to use
	test-groff as groff with an environment variable.

	* src/roff/nroff/tests/verbose_option_works.sh.in: Rename to...
	* src/roff/nroff/tests/verbose_option_works.sh: ...this.  Check
	the nroff version being tested against the groff version being
	wrapped.  This exposes a bug; the system groff rather than the
	build tree groff was being invoked.  Refactor.  Stop messing
	with @GROFF_BIN_PATH_SETUP@ (enabling the rename); instead, let
	test-groff handle that for us.  Locate it and export the
	variable GROFF_TEST_GROFF so nroff can find it.  Because we
	manipulate $PATH to run the tests, the $PATH of an installed
	groff system will _always_ differ from that used by a build
	tree; ignore it in the test cases.  Dispose of bashisms and set
	shebang to /bin/sh.

	* src/roff/nroff/nroff.am: Stop generating the above test
	script.  It can now be run as it ships.

	Make our assert() C99-conformant.

	groff has its own implementation of the standard C library's
	assert() macro.  It hasn't been updated since C89.  C99 requires
	that the diagnostic emitted by assert() contain the failing
	expression and name of the function in scope.

	* src/include/assert.h: Add additional pointer to const char
	arguments to do_assert() and assertion_failed() for function
	name and stringified expression.
	(assertion_failed): Update prototype.
	(do_assert): Accept 'func' and 'msg' parameters and pass them to
	assertion_failed().
	(assert): Update macro to collect '__func__' and stringify the
	expr parameter (as 'msg') and pass them do do_assert().
	* src/libs/libgroff/assert.cpp (assertion_failed): Rewrite
	diagnostic to more closely match GNU Coding Style format and
	also report function and failing expression.

	Example output:
		troff: ../src/roff/troff/input.cpp:2644: do_request():
		assertion failed: '0 == "But first, here's a rotten old
		BBC programme."'

	We have no excuse to assert(0) ever again.  Express the
	invariant that has been violated.

2020-04-11  G. Branden Robinson <g.branden.robinson@gmail.com>

	Enable backtracing across process/file boundaries when errors or
	non-ignored warnings are encountered.

	Experimentation reveals that .so, .mso, and .pso requests acted
	as barriers to backtracing except when explicitly requested with
	the .backtrace request.  Judging by the git history, this
	behavior dates back to June 1991 or earlier.  The intention,
	according to a source comment, was only to suppress the
	backtrace output for the line corresponding to the outermost
	level of the input stack (commonly, a file argument to groff).
	Unfortunately, that wasn't its only effect.

	This change does result in one additional line of output for
	each error or (non-ignored) warning when -b is given.  However,
	I regard this as unobjectionable because {1} a backtrace was in
	fact explicitly requested; and {2} it seems a poor tradeoff to
	suppress most of the backtrace in some complicated and
	frustrating cases for the sake of one fewer line of backtrace
	output in a trivial one.

	Now, backtracing behaves the same no matter what triggers it.

	Fixes Savannah #58153.

	* src/roff/troff/input.cpp (file_iterator::backtrace): Call
	get_location() for its side effect of rewriting a filename of
	"-" to "<standard input>", for consistency with other diagnostic
	messages.  (In this class, this member function always returns
	1, so ignore the return value.  This fact is an essential part
	of what led to the bug; the conditional
		p && !p->get_location(0, &f, &n)
	which appeared in the for loop of input_stack::backtrace() prior
	to this change would always evaluate to false when a node of the
	file_iterator class was encountered.)
	(input_stack::backtrace): Replace member function body with that
	of input_stack::backtrace_all().
	(input_stack::backtrace_all): Delete.
	(backtrace_request): Update the only call site of the above.

	* src/roff/groff/tests/regression_savannah_58153.sh: Add test.
	* src/roff/groff/groff.am (groff_TESTS): Run test.

	* src/roff/groff/tests/string_case_xform_errors.sh: Update

2020-04-10  G. Branden Robinson <g.branden.robinson@gmail.com>

	Reorganize backtrace output.

	* src/roff/troff/input.cpp (string_iterator::backtrace):
	Prefix the output with the program name if it is known.  In a
	deviation from the GNU Coding Standards, put the string
	"backtrace:" immediately next instead of the file and line
	number; this is because, particularly in cases where the
	backtrace is most interesting or needed, it will produce
	multiple lines of output and the common prefix aids visual
	understanding.
	(file_iterator::backtrace): As above; also, change prefix for
	popened nodes in the iterator from "process" to "pipe".  This
	seemed preferable to omitting the information entirely or using
	an inscrutable sigil like 'f' or 'p'.  The advantage is that the
	output is better aligned--better ergonomics for those who have
	to cope with a lot of it.  Furthermore, output the filename only
	once.

	Example of old and new output:

	/tmp/inner:2: backtrace: file '/tmp/inner'
	echo .so /tmp/inner:1: backtrace: process 'echo .so /tmp/inner'
	/tmp/outer:1: backtrace: file '/tmp/outer'

	troff: backtrace: file '/tmp/inner':2
	troff: backtrace: pipe 'echo .so /tmp/inner':1
	troff: backtrace: file '/tmp/outer':1

2020-04-10  G. Branden Robinson <g.branden.robinson@gmail.com>

	* src/roff/troff/input.cpp (read_size): Add units to diagnostic.
	This function works only with device-specific basic units
	internally; users likely think in terms of point size, so add
	the basic unit suffix "u" to offer a hint about what's going on.

	Example:
	$ groff -ww >/dev/null
	\s[10]A\s[-12]B
	troff: <standard input>:1: warning: point-size escape results in
	non-positive size -2000u; set to 1u

	On a PostScript device with 1000 basic units to the point, the
	difference is important and would be confusing without the unit
	indication.

2020-04-08  G. Branden Robinson <g.branden.robinson@gmail.com>

	Correct and clarify point size documentation.

	Our Texinfo manual has long documented the request '.ps 0' as
	restoring the previous point size (just as '\s0' or '.ps' with
	no argument does), but this is incorrect; since groff 1.02 or
	earlier (June 1991), the request has not actually worked this
	way.  Instead, '.ps 0' sets the point size to 1 basic unit
	{though output drivers may clamp this to a higher value}.  This
	behavior is consistent with AT&T troff, Hierloom Doctools troff
	and, per Ingo Schwarze, Plan 9 troff.  (It is, however, not
	consistent with neatroff.)

	* doc/groff.texi (Changing Type Sizes): Stop claiming that '.ps
	0' works like '\s0'.  Note that the resulting (computed) point
	size, not the argument, is clamped.  Note that it is
	non-positive, not negative, point sizes that are clamped to 1u.
	Add (forward) cross-reference to section where \n[.ps] is
	defined since it is mentioned here.  Move explanation of special
	handling of zero argument to \s escape description.

	* man/groff.7.man (Request short reference): Explain .ps N
	independently of \s.  Note clamping behavior.

2020-04-04  G. Branden Robinson <g.branden.robinson@gmail.com>

	* src/roff/troff/input.cpp (read_size): Move special-case
	interpretation of the '\sN' form of point-size escapes when 'N'
	is 1, 2, or 3 to compatibility mode (groff -C) only, and throw
	error diagnostic with suggestion for remedy if encountered.

	Traditionally, '\s36A' is interpreted as "set point size to 36,
	then emit 'A'".  However, only values in the range 10-39 are
	handled specially; '\s40A' is interpreted as a four-point "0A".
	This is unlike anything else in *roff grammar; see \*, \$, \f,
	\F, \g, \k, \m, \M, \n, \V, \Y, and \z.

	To anticipate objections: Why not throw only a warning?  Because
	there isn't a warning category for supported but ambiguous
	syntax (this behavior of AT&T troff dates back to the mid-1970s
	but was not documented in the Troff User's Manual until 1992).
	Why not throw the error outside of compatibility mode too?
	Because outside of compatibility mode we (now) have an
	unambiguous parse.

	Background: The Graphic Systems C/A/T phototypesetter (the
	original device target for AT&T troff) only supported a few
	discrete point sizes in the range 6..36, so Ossanna
	special-cased the parser to do what the user must have meant.
	Kernighan warned of this in the 1992 revision of CSTR #54
	{§2.3}, and more recently, McIlroy referred to it as a "living
	fossil".

	Improve point-size escape diagnostics.

	* src/roff/troff/input.cpp (read_size): Disclose context
	{point-size escape intepretation} in diagnostic messages.  When
	a "bad digit" is encountered, describe it if possible.  When a
	relative adjustment results in a negative point size, report the
	computed value.  Also rename a variable for slightly more
	clarity ("bad" does not refer to all bad parses, just some cases
	of bad digits), and update an insufficiently generalized comment
	{"\s(00" is also an acceptable expression for point-size zero}.

	Based on suggestions by Ingo Schwarze and Bjarni Ingi Gislason.

	Stop ms macro package from manipulating warnings.

	* tmac/s.tmac: Remove code block that attempted to enable all
	warnings "only if none are given on the command line".  It did
	this by simply comparing the value of the warn 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 ms document or pass "-w w" to groff (see
	troff(1) or our Texinfo manual for more on warnings).

	Thanks to Bjarni Ingi Gislason for bringing this issue to our
	attention.

	Accept any number of arguments for .Dd in the groff_mdoc(7)
	macros.

	* tmac/doc-common-u: The .Dd macro behaved in a weird way:
	Without arguments, it printed the string "Epoch".
	With one, two, four, or more arguments, it ignored all arguments
	and used the current date instead.
	Only for exactly three arguments, it printed the arguments.
	None of this made sense.  Giving the date as "Epoch" is
	absurd, and printing the current date is just misleading:
	why should a document be considered up-to-date when the author
	did not even bother to state the date of the last change?
	Admittedly, the behaviour for 0 and 4 or more arguments
	already appeared 4.3BSD-Reno, and the behaviour for 2 or 3
	arguments in 4.4BSD.  But it was already wrong even in those
	days: several manual pages in 4.4BSD gave .Dd a single, quoted
	argument, e.g. .Dd "June 9, 1993": cap_mkdb(1), id(1), sed(1),
	err(3), getcap(3), sysctl(3), amd(8), disklabel(8), and others.
	Consequently, simply print all the arguments, no matter how
	many there are.

	This bug was found by Jonathan Gray <jsg@openbsd.org>
	while he looked at 4.xBSD manual pages.

2020-01-16  Ingo Schwarze  <schwarze@openbsd.org>

	Repair .AT and .UC in the groff_man(7) macros.

	* tmac/an-old.tmac: Setting user-defined strings in a macro that
	will later be called indirectly from page location traps is
	excessively complicated.  Besides, the implementation doesn't
	work: when the trap is finally sprung, the defaults from the
	an-init macro clobber what the author specified with .AT or .UC.
	Instead, all that is needed is setting the strings for the
	header before triggering the page break, such that they appear
	right away, while setting the strings for the footer after the
	page break, such that they don't appear on the previous page.

	This bug was found by Jonathan Gray <jsg@openbsd.org> while he

	The an (man) macro package supports new CS and CT number
	registers to control rendering of man page section headings and
	titles, respectively, in full capitals.  These default off (with
	no visible effect on pages which already fully capitalize these
	strings in man page sources).  The rationale is to encourage man
	page authors to preserve case distinction information in (or
	restore it to) their titles and section headings, while giving
	users (including system administrators, distributors,
	integrators, and maintainers of man(1) implementations) a way to
	view the rendered page elements in full capitals if desired.

	* tmac/an-old.tmac (TH/an-init): If number register CT is
	defined and nonzero, call .stringup on \*[an-title].
	(SH): Store macro argument list to \*[an-section-heading].  If
	number register CS is defined and nonzero, call .stringup on it.

2019-06-28  G. Branden Robinson <g.branden.robinson@gmail.com>

	devlatin1: Map \(oq to ' on output.

	* font/devlatin1/R.proto: Render the output glyph \[oq]
	{opening quote} as 0x27 (apostrophe) instead of 0x60 (grave
	accent).  A grave accent is just flat wrong for the Latin-1
	character set, a.k.a. ISO 8859-1.  The defining document ECMA-94
	{June 1986} is freely available for perusal.  The ECMA-94 Latin
	character sets do not define any glyphs for directional
	{"typographer's"} quotation marks, but the apostrophe is
	depicted as a neutral (vertical) glyph, whereas the grave accent
	0x60 and acute accent 0xB4 are mirror-symmetric diacritical
	marks.

	Note that this change has no effect on _input_ conventions for
	roff source documents.  You can still get directional single
	quotes on UTF-8, PostScript, PDF, and other output devices
	supporting them by typing sequences like `this' in the input
	{character remapping with ".char" requests and similar
	notwithstanding}.

	Patch and idea from Ingo Schwarze, who originally proposed it
	for ASCII as well, and included Latin-1 for parallelism.
	The groff developers could reach no consensus about the wisdom
	of such a change for ASCII (which was designed to support
	ambiguity for some code points, requiring the development of
	supplementary interpretation conventions between parties).
	ECMA-94/ISO-8859 is more strongly prescriptive.

	See https://savannah.gnu.org/bugs/?55616 and the groff mailing
	list archives for 31 January to 23 February 2019 at
	https://lists.gnu.org/archive/html/groff for lengthy discussion.

2018-12-18 Bertrand Garrigues <bertrand.garrigues@laposte.net>

	Fix 'dvi' and 'pdf' texinfo doc generation.

	GNU make has a built-in variable 'TEXI2DVI' but it is not the case
	of all 'make' implementations, which causes 'make doc' to fail
	with an unclear message although 'texi2dvi' is available.  Also,
	'texi2dvi' is invoked inconditionnally.

	* m4/groff.m4 (GROFF_TEXI2DVI): new macro to detect properly the
	presence of 'texi2dvi'.

	* configure.ac: use 'GROFF_TEXI2DVI' and define automake conditional
	'HAVE_TEXI2DVI'.

	* doc/doc.am:
	- Define TEXI2DVI to 'texi2dvi'.
	- Print an error message if 'texi2dvi' is not available.

2018-12-14  G. Branden Robinson <g.branden.robinson@gmail.com>

	* doc/groff.texi: Drop documentation of "man" macro package from

	  duplicated from groff_man(7)--on use of man.local (including
	  examples of Ultrix-compatible macros) are retained.

2018-12-08 Bertrand Garrigues <bertrand.garrigues@laposte.net>

	Install texinfo doc on 'make install-pdf' and 'make install-html'

	* doc/doc.am:

	- New rules 'uninstall_pdf' and 'uninstall_html'.
	- Use $(RM) instead of 'rm'.
	- Don't try to build doc if 'BUILD_INFODOC' is not set.
	* INSTALL.REPO: document texinfo build and installation.

2018-12-10 Ingo Schwarze <schwarze@openbsd.org>

	Remove gnulib's hypot module.

	The removal of 'GROFF_NEED_DECLARATION([hypot])' in 'configure.ac'

	* bootstrap.conf: do it.

2018-12-08  Deri James  <deri@chuzzlewit.myzen.co.uk>

	Problem running gropdf on big endian (Sparc)

	* src/devices/gropdf/gropdf.pl: Prior to perl v5.9 the 'L<'
	template for 'unpack' was unavailable. Solaris 10 uses v5.8.4
	so safer to use the template 'V' rather than 'L<'.

2018-12-08 Bertrand Garrigues <bertrand.garrigues@laposte.net>

	Use gnulib's 'hypot' module.

	In 'configure.ac', the macro call
	'GROFF_NEED_DECLARATION([hypot])' checks whether the function
	'hypot' is correctly declared in 'math.h', but the test is buggy
	and may yields false results.

	not available.

	* contrib/mom/mom.am: distribute inconditionnally test-mom.in.

	* m4/groff.m4 (GROFF_URW_FONTS): check if 'awk' and 'gs' are

	tmac/sv.tmac: Set Swedish hyphenation flags to 32.

	This permits hyphenation after the first character but continues
	prohibiting it before the last character of a word, in
	congruence with the TeX-based hyphenation patterns we use.

	Fixes <https://savannah.gnu.org/bugs/index.php?55066>.

	Fix build on environment where /etc/papersize contains comments

	Issue introduced on commit efea81c75f831ddc6717c2ef25556e0f49d1f679.

	* m4/groff.m4 (GROFF_PAGE): remove comments and get the 1st string
	of '/etc/papersize'.

2018-11-12  G. Branden Robinson <g.branden.robinson@gmail.com>

	* m4/groff.m4 (GROFF_PAGE): Try /etc/papersize first.

2018-11-12  G. Branden Robinson <g.branden.robinson@gmail.com>

	* bootstrap.conf: Bump Autoconf dependency to 2.68.  We need it
	to support our bug-reporting URL, which contains a "?".
	Strictly, Autoconf 2.65 is fine, but 2.66 and 2.67 broke this.
	Even 2.69 is over 6 years old now.

	See <https://savannah.gnu.org/support/?107450>.

2018-11-12  G. Branden Robinson <g.branden.robinson@gmail.com>

	* m4/groff.m4 (GROFF_PAGE): Quote shell variables that are under
	external control and may contain embedded whitespace.  A test
	shows that our configure script is now robust in this way, but
	our Automake files are not, starting with
	src/utils/afmtodit/afmtodit.am.

2018-11-12  G. Branden Robinson <g.branden.robinson@gmail.com>

	* makevarescape.sed:
	  - Escape plain spaces and double-quotes (ASCII 32 and 34) so
	    that bad things don't happen if they are embedded in a Make
	    variable expanded in a man page @THUS@ _and_ given as an
	    argument to a macro that distinguishes its parameters, such
	    as .IR.
	  - Add discretionary breaks after groups of slashes not
	    preceded by a space; e.g., transform "/usr/bin/groff" into
	    "/usr/\:bin/\:groff".  Will also work on URLs
	    {"https://\:example.com/\:page.html"} in case we need that.

	Stop spelling "Unix" as "UNIX".

	Per AT&T Bell Labs veterans Doug McIlroy and Meg McRoberts,
	spelling "Unix" in full caps was a contrivance insisted upon by
	AT&T lawyers, and not a practice used in the Unix manuals
	themselves or the Bell Labs Technical Journal.  See
	  https://lists.gnu.org/archive/html/groff/2015-01/msg00026.html
	and
	  https://lists.gnu.org/archive/html/groff/2015-01/msg00029.html
	for support.

	There are instances I did _not_ change; they may require further
	review.
		ChangeLog.*
		NEWS
			One reference relevant to mdoc; see below.
		doc/meintro{,_fr}.me
			These documents also give the small caps
			treatment to groff, troff, and nroff, suggesting
			a separate changeset.
		src/preproc/pic/pic.ypp
			Contains a comment referring to "Compaq Tru64
			UNIX"; not worth the candle IMO.
		tmac/s.tmac:
			{ms macro package} Leaving UX macro definition
			alone until/unless it can be established that
			this doesn't change the rendering of historical
			documents in an objectionable way.
		tmac/doc-syms-u:
		tmac/doc-old.tmac-u:
		tmac/doc-common-u:
		tmac/groff_mdoc.7.man:
			{mdoc macro package} Similar; mdoc defines many
			strings that spit out "UNIX" (albeit not with a
			font size change).

	man pages: Escape interpolated Make variables.

	* makevarescape.sed: Transform - to \-, ~ to \(ti, and so forth,
	{with an extra layer of backslashes--see below} so that Makefile
	variables containing ASCII characters that do not represent
	themselves literally in *roff (see groff_char(7)) are correctly
	interpolated into man page text.

	* Makefile.am (.man): Transform Makefile variables with the
	above script when interpolating them into man page text.

	Note that while the script, combined with this target, will
	transform ` to \(ga, including grave accents in Makefile
	variables is likely to fail when the shell lexes the argument to
	echo within the old-style command substitution ``.  Testing
	shows that grave accents should work[1] if POSIX-style command
	substitution $() is done instead.  However, $() is less
	portable.  (Triple-escaping grave accents \\\` inside the
	interpolated Makefile variable will work, but is not attempted
	at present.)

	Note also that the amount of backslash-escaping in the sed
	script is excessive (and incorrect) for normal purposes, but
	required here because a command substitution is being nested
	inside yet another invocation of sed.

	{1} For this target; no assurances about the good behavior of
	unusual characters in Makefile variables in other aspects of the
	groff build are offered.

	Fixes <https://savannah.gnu.org/bugs/index.php?55004>.

2018-11-06  G. Branden Robinson <g.branden.robinson@gmail.com>

	* src/utils/lookbib/lookbib.cpp: Doesn't make much sense to mark
	Version_string as a C extern if you're just going to hide it in
	a throwaway scope again.  Remove braces, exposing it.

	"lookbib -v" now reports a version number, instead of "(null)".

	Fixes <https://savannah.gnu.org/bugs/index.php?54972>.

2018-11-06  G. Branden Robinson <g.branden.robinson@gmail.com>

	* src/libs/libgroff/error.cpp (do_error_with_file_and_line):
	If:
	  a program name is known;
	but
	  no file is being processed or the line number is negative,
	then there was no space between the program name (with colon),
	and the succeeding diagnostic message.

	Example: lookbib:fatal error: no databases

	Fixes <https://savannah.gnu.org/bugs/index.php?54971>.

2018-11-05  G. Branden Robinson <g.branden.robinson@gmail.com>

	Make strip.sed operate only if given permission.

	* tmac/strip.sed: Do nothing whatsoever to any input file that
	lacks a line matching "%beginstrip%".  This implements a
	contract between the macro file writer and the stripper script
	{roff input is not parseable with crude weaponry like regular
	expressions}.  In practice, most of the changes performed by the
	script were already in a block enforcing this.  My changes:
	- Stop unconditionally inserting a roff comment noting the
	  reader of stripping at line 2.  Instead, replace the line
	  matching "%beginstrip%" with this comment if and only if it
	  is present.
	- Stop deleting lines containing only the empty request if
	  they occur before "%beginstrip%".
	- Tweak the wording of the roff comment.
	- Remove comment within the sed script; see
	  https://lists.gnu.org/archive/html/groff/2017-11/msg00057.html
	  and the sed section of "Limitations of Usual Tools" in the
	  GNU Autoconf Manual.

	Invalidates <https://savannah.gnu.org/bugs/index.php?53784>.

2018-11-04  G. Branden Robinson <g.branden.robinson@gmail.com>

	* tmac/an-old.tmac: When emitting diagnostics, report the name
	of the macro file complaining, and the name and line number of
	the input file at the time of trouble.  Thanks to Bjarni Ingi
	Gislason for part of the patch.

	Fixes <https://savannah.gnu.org/bugs/?54175> and continues the
	long process of fixing <https://savannah.gnu.org/bugs/?52463>.

2018-11-04  G. Branden Robinson <g.branden.robinson@gmail.com>

	* doc/meintro_fr.me: Add encoding hint to top of file so preconv
	works correctly even if the build environment's encoding is not
	UTF-8.  Adapted from Bjarni Ingi Gislason's patch.  Also add
	long-form Emacs coding declaration at end of file.  Vim's
	auto-detection seems to be fine, so did not update its modeline.

	Fixes <https://savannah.gnu.org/bugs/index.php?54530>.

2018-11-04  G. Branden Robinson <g.branden.robinson@gmail.com>

	* tmac/groff_man.7.man: Reorganize and largely rewrite to more
	precisely document the macro package's behavior and to be more
	helpful and accessible to man page writers who may never read
	any other groff documentation.

2018-10-25  G. Branden Robinson <g.branden.robinson@gmail.com>

	Clarify meaning of \p escape.  Also make more explicit that line
	adjustment for the .brp request and \p escape depends on the
	current adjustment mode.

	* doc/groff.texi: Clarify that \p has effect at the next word
	boundary.  Thanks to Dave <barx> for pointing out the issue and
	providing elucidating language.

	* man/groff.7.man: Similar, but terser.

	Fixes https://savannah.gnu.org/bugs/index.php?54894.

2018-10-04  Deri James  <deri@chuzzlewit.myzen.co.uk>

2018-10-10  Bertrand Garrigues <bertrand.garrigues@laposte.net>

	Update 'gnulib' submodule.

	* gnulib: now points on dce8759f0f0236a860a3e68b63c5e99cc6f168f9
	from 'gnulib' repository.  This fixes build error with glibc 2.28

	* tmac/tty-char.tmac: add playing card suits

2018-08-16  Ingo Schwarze  <schwarze@openbsd.org>

	* src/preproc/preconv/preconv.1.man: add -D to the SYNOPSIS

2018-08-09  Ingo Schwarze  <schwarze@openbsd.org>

	* Makefile.am: correctly calculate MAJOR_VERSION etc.

2018-06-19  Deri James  <deri@chuzzlewit.myzen.co.uk>

	Fixes to gropdf

	* src/devices/gropdf/gropdf.pl: Make default line width 0.4pt
	to match grops. Use 'S' operator (stroke) rather than 's' (close
	and stroke) when Dl command received. Improve switching between
	text and graphic modes.

2018-07-01 Bertrand Garrigues <bertrand.garrigues@laposte.net>

	Problem reported by Pali Rohár <pali.rohar@gmail.com>.

	  http://lists.gnu.org/archive/html/groff/2018-05/msg00088.html

	* font/devdvi/texitt.map: New file.  This is identical to
	`textt.map' except the dollar glyph, which gets replaced by the
	pound glyph.

	* font/devdvi/generate/Makefile (CWI): Use `texitt.map'.

	* font/devdvi/CWI: Regenerated.

2018-05-07  G. Branden Robinson <g.branden.robinson@gmail.com>

	Improve diagnostics on bad hyphenation requests.

	* src/roff/troff/env.cpp: Add new HYPHEN_* symbols to anonymous
	enum.

	* src/roff/troff/env.cpp (hyphenate_request):
	  - Warn about hyphenation request values that are completely
	    out of range.
	  - Report bad hyphenation request value in diagnostic messages.

2018-04-28  G. Branden Robinson <g.branden.robinson@gmail.com>

	grap2graph: Parallelize changes with pic2graph.

	* contrib/grap2graph/grap2graph.sh:
	  - Refactor temp directory handling.
	  - Handle embedded whitespace in temp dir.
	  - Adapt to old convert(1) programs.

	* contrib/grap2graph/grap2graph.1.man: Make editorial/style
	changes and minor corrections.

2018-04-26  G. Branden Robinson <g.branden.robinson@gmail.com>

	eqn2graph: Remove -unsafe option.

	* contrib/eqn2graph/eqn2graph.sh: Unrecognize "-unsafe" option
	and eliminate $groff_opts variable.  As far as I can tell, this
	option had no effect because (1) pic is not run on the input
	stream (no -p argument to groff); (2) eqn doesn't support
	"shelling out" as pic does; and (3) there is no way to embed
	*roff requests inside a sequence of eqn commands.  If I'm wrong,
	let me know.

	* contrib/eqn2graph/eqn2graph.1.man: Undocument "-unsafe"
	option.

2018-04-26  G. Branden Robinson <g.branden.robinson@gmail.com>

	eqn2graph: Parallelize changes with pic2graph.

	* contrib/eqn2graph/eqn2graph.sh:

	* contrib/eqn2graph/eqn2graph.1.man: Make editorial/style
	changes and minor corrections.

2018-04-25  G. Branden Robinson <g.branden.robinson@gmail.com>

	pic2graph: Refactor temp directory handling.

	* contrib/pic2graph/pic2graph.sh: Issue a diagnostic and give up
	if the user's desired temporary directory does not exist.  Also
	document the Bashism $RANDOM and work around its absence.

2018-04-25  G. Branden Robinson <g.branden.robinson@gmail.com>

	pic2graph: Handle embedded whitespace in temp dir.

	* contrib/pic2graph/pic2graph.sh: Quote shell variables having
	to do with the temporary directory's location; without
	quotation, temporary directory names with embedded whitespace
	are wrongly handled.

2018-04-24  G. Branden Robinson <g.branden.robinson@gmail.com>

	* doc/groff.texi: Bump end of copyright range to 2018.  Werner
	added substantial text this year about hyphenation.

2018-04-24  G. Branden Robinson <g.branden.robinson@gmail.com>

	Set version to 1.22.4 in the few places that hard-code it.

	* arch/mingw/grap2graph.cmd:
	* contrib/groffer/version.sh:
	* doc/groff.texi:
	* doc/webpage.ms: Bump from 1.22.3 to 1.22.4.

2018-04-24  Deri James  <deri@chuzzlewit.myzen.co.uk>

	Restrict scaling factors to 3dp and better handle CR/LF in import.

	* src/devices/gropdf/gropdf.pl: Restrict scaling factors to 3dp
	rounded. If pdf imported with pdfpic uses CR/LF line termination
	ibclude XObject Image, length of stream out by 1.

2018-04-23  G. Branden Robinson <g.branden.robinson@gmail.com>

	man pages: Shorten version footer.

	* **/*.man: Replace "Groff Version" with "groff" in the fourth
	argument to .TH in all man pages.  This suffices to keep that
	part of the footer from overrunning the date, even in dirty
	trees on 80-column terminals.

	Fixes https://savannah.gnu.org/bugs/index.php?53721.

2018-04-23  G. Branden Robinson <g.branden.robinson@gmail.com>

	pic2graph(1): Make editorial/style changes and minor
	corrections.

2018-04-23  G. Branden Robinson <g.branden.robinson@gmail.com>

	pic2graph: Adapt to old convert(1) programs.

	* contrib/pic2graph/pic2graph.sh: Grep convert's -help output
	for the string "-trim".  If it is not found, the old method for
	image trimming documented in pic2graph's man page, "-crop 0x0",
	is used.  I am motivated by the fact that the warning about this
	in our man page is very old (10 years or more), and I wanted to
	get rid of it.

	pic2graph emits a warning when performing this fallback, in the
	event the ImageMagick and/or GraphicsMagick teams surprise the
	world again.

	* contrib/pic2graph/pic2graph.1.man: Remove BUGS section, the
	entire contents of which was dedicated to convert's change in
	behavior.

2018-04-22  G. Branden Robinson <g.branden.robinson@gmail.com>

	groff_man(7): Expand command synopsis section.

	This section now explains in detail how to write (and read) a
	command synopsis.

2018-04-12  Deri James  <deri@chuzzlewit.myzen.co.uk>

	Make PDFPIC behave the same whether -Tps or -Tpdf used.

	Previously the -Tpdf version did not cause a break nor position
	to the line beneath the imported picture, whilst the -Tps
	version did.

	* tmac/pdfpic.tmac: Corrected behavior.

	* NEWS: Explain the change of behaviour and how to reinstate
	the previous behaviour using register PDFPIC_NOSPACE or the
	environment variable GROFF_PDFPIC_NOSPACE.

2018-03-27  Bertrand Garrigues <bertrand.garrigues@laposte.net>

	Define a short version for data installation dir name.

	This is the full version stripped of any characters after the
	third digit.  Used for installation of font, macro and various
	data (by default in /usr/local/share/groff).  The various programs
	and scripts still use the full version from gnulib script
	'git-version-gen' .

	* configure.ac (SHORT_VERSION): short version definition.

	* Makefile.am: use 'SHORT_VERSION' for 'docdir' and 'datasubdir'
	definitions.

2018-03-11  Bertrand Garrigues <bertrand.garrigues@laposte.net>

	Remove doc/automake_migration_tests.txt

	Automake migration was completed long time ago and this file is no
	longer needed.

2018-03-11  Colin Watson  <cjwatson@debian.org>

	Switch to Gnulib implementation of snprintf

	This is more actively maintained, straightforward to integrate now
	that we have Gnulib integration, and simplifies groff's overall
	licensing.

	* bootstrap.conf (gnulib_modules): Add `snprintf' and `vsnprintf'.
	* configure.ac: Remove local checks for `snprintf' and `vsnprintf'.
	* Makefile.am: Remove various comments related to local checks for
	`snprintf' and `vsnprintf'.
	* src/include/lib.h: Remove declarations of `snprintf' and
	`vsnprintf'.
	* src/libs/libgroff/libgroff.am (EXTRA_DIST): Remove
	`src/libs/snprintf/snprintf.c'.
	* src/libs/snprintf/snprintf.c: Remove.

	* LICENSES: Remove section about `src/libs/snprintf/snprintf.c'.
	* MANIFEST: Remove entry for `src/libs/libxutil'.

2018-03-09  Deri James  <deri@chuzzlewit.myzen.co.uk>

	PDF must not open in presentation mode.

	* src/devices/gropdf/gropdf.pl: When GROPDF_NOSLIDE=1
	passed do not set pdf to presentation mode.

2018-03-09  Deri James  <deri@chuzzlewit.myzen.co.uk>

	Allow a "." to signify a missing parameter in .pdftransition

	* src/devices/gropdf/gropdf.1.man: Explain the .pdftransition
	macro (and underlying '\X' command) accepts a "." to specify
	a parameter retains its current value.

2018-03-09  Colin Watson  <cjwatson@debian.org>

	man pages: fix incorrect cross-referenced section

	* man/roff.7.man (FILE NAME EXTENSIONS): Correct reference to
	groff_filenames(5).

2018-03-09  Colin Watson  <cjwatson@debian.org>

	mdate.sh: rewrite in Perl

	groff already requires perl to build.  This version is much shorter
	and easier to understand than the shell/awk version: we don't have
	to worry about convincing ls to produce output that we can parse,
	and we don't have to play games with the way that the same field may
	contain either the year or the time depending on how old the file
	is.

	While I'm at it, this version also adds `SOURCE_DATE_EPOCH' support
	for reproducible builds: when `SOURCE_DATE_EPOCH' is set, files are
	considered to have been last modified at that time.

	* mdate.sh: Rewrite in Perl, moving to ...
	* mdate.pl: ... this new file.
	* Makefile.am (EXTRA_DIST, .man): Update references.

2018-03-09  Colin Watson  <cjwatson@debian.org>

	Remove #! lines from non-executable files

	These are always invoked by the build system (either in-tree or via
	the installed Makefiles) using the necessary program, so the #!
	lines were unnecessary.  They were harmless except that they caused

	doc: stop generating W3C validation icons

	Debian's `lintian' tool says:

	  These badges may be displayed to tell readers that care has been
	  taken to make a page compliant with W3C standards.  Unfortunately,
	  downloading the image from www.w3.org might expose the reader's IP
	  address to potential tracking.

	I think the risk is a small one, but I also don't think the badges
	are especially valuable, so it doesn't seem like much to ask to just
	drop them at least for groff's own documentation.

	* doc/doc.am (.ms.html, doc/pic.html): Remove `-P-V' option.

2018-03-01  Deri James  <deri@chuzzlewit.myzen.co.uk>

	Place pdf in presentation mode if new commands used.

	* src/devices/gropdf/gropdf: The new commands which
	control page transitions should result in the pdf being
	opened in presentation mode.

2018-03-01  Werner LEMBERG  <wl@gnu.org>

2018-02-02  Bertrand Garrigues <bertrand.garrigues@laposte.net>

	Use gnulib script 'git-version-gen' to define groff's version

	* bootstrap.conf: add 'git-version-gen' script.

	* configure.ac: suppress 'GROFF_VERSION_STRING' and replace it by
	the script.  If the current commit corresponds to a tag, then the
	version is simply the tag name.  Otherwise the version has the
	format: <tag>-<nb_commits_from_latest_tag>-<commit sha1>.  The
	version is now stored in '.version'.

	* REVISION: removed.

	* VERSION: removed.

	* Makefile.am: define 'MAJOR_VERSION', 'MINOR_VERSION' and
 	'REVISION'.

	* src/libs/libgroff/libgroff.am: use 'MAJOR_VERSION',

2018-01-17  Deri James  <deri@chuzzlewit.myzen.co.uk>

	All values should be 3 decimals

	* src/devices/gropdf.pl: for values approaching zero values
	in the for 0.nnnnnnE-nn could be written, not valid syntax for
	PDF. Make all values rounded to 3 decimals, becomes 0.000.

	Also changed stream Filter dictionary entry to an array.

	[mdoc]: rewrite the implementation of the .Lk macro

	* tmac/doc.tmac-u (Lk): Rewrite.

	The old implementation was written before the big mdoc
	rewrite for groff-1.17.  In contrast to most other macros,
	it was never updated to use the new techniques.
	This new implementation makes .Lk callable, makes trailing
	punctuation work in the normal way, and makes the style of
	the implementation consistent with other macros.

	It also removes the feature of automatically switching
	between in-line and displayed rendering depending on the
	length of the link because that was inconsistent across
	output modes and counter-intuitive, resulting in ugly
	output for many existing real-world manual pages.
	It now always renders in-line.  Use .D1 Lk where desired.

	Merging http://savannah.gnu.org/bugs/?52849
	OK wl@gnu, jmc@openbsd, bentley@openbsd

2017-12-14  G. Branden Robinson <g.branden.robinson@gmail.com>

	man pages: Comment compatibility-mode switching.

	The '.do' and '.cp' requests (both groffisms) are some of the
	more obscure features of groff's own man page corpus.
	Consequently, they get cargo-culted around, within and outside
	groff.  Thanks to Werner Lemberg for the discussion, which
	revealed (to me) that groff ships with compatibility mode on by
	default on Solaris 10 and 11.

	Fix bug https://savannah.gnu.org/bugs/?52444.

2017-11-30  G. Branden Robinson <g.branden.robinson@gmail.com>

	Msg().

	Fix part of bug https://savannah.gnu.org/bugs/?52463.

2017-11-21  G. Branden Robinson <g.branden.robinson@gmail.com>

	man pages: Fix compatibility-mode problems.

	* contrib/gperl/gperl.1.man: Use idiomatic .BI macro instead of
	  leading an input line with a font escape followed by a dot,
	  the interpretation of which differs based on compatibility
	  mode.

	* src/preproc/soelim/soelim.1.man: Make .mso request only after
	  compatibility mode is turned off.

2017-11-19  G. Branden Robinson <g.branden.robinson@gmail.com>

	* Makefile.am: Protect arguments to "tr" from globbing.

	Prevents errors from tr during man page generation and possible

	the build tree.

	and string names unintentionally caught some mom stuff.
	Harmlessly in this instance, but with potentially surprising
	future effects.  Remove (only) this substitution per discussion

	* tmac/tty-char.tmac: Switch the policy from trying to imitate the
	characters' graphical shapes, which resulted in unintelligible
	renderings in many cases, to transliterations conveying the
	characters' meanings.  One benefit is making these characters
	usable for portable manual pages.

	'gropdf' does not correctly load new ghostscript fonts

	See bug at: https://savannah.gnu.org/bugs/?50989. Since ghostscript
	9.21 the fonts supplied have changed from .pfb to .pfa type (with a
	raw binary section). These failed to be properly loaded.

	Fix build if `configure' check for `fprintf-posix' fails.

	See bug at: https://savannah.gnu.org/bugs/?51554.  If tests for
	posix compliance of fprintf from `gnulib_m4/fprintf-posix.m4'
	fail, a replacement function of `fprintf' is used.  Consequently,
	all executables that use this function must link against the
	gnulib (`libgnu.a').  The bug was introduced by commit
	fa41eeba06987a12bc0434f8b51896d4618a3997.

	* src/devices/gropdf/gropdf: Further 'fix' to handle those octal

	See bug at: https://savannah.gnu.org/bugs/?51568
	
	* src/devices/gropdf/gropdf: previous 'fix' was too narrow, all
	'\' characters should be escaped. Also there was an unwanted 
	interaction with code in routine 'do_t'. Sometimes, do_C, when 
	the named glyph is mapped to a chr < 32, this is encoded as octal
	\nnn, so in this case the '\' must not be escaped.
	
2017-07-25  Deri James  <deri@chuzzlewit.myzen.co.uk>

	If input text contained string which could be interpreted as
	escaped octal (\ddd) a pdf viewer would interpret as an octal
	character.  See bug at: https://savannah.gnu.org/bugs/?51568
	
	* src/devices/gropdf/gropdf: protect text which resembles \ddd
	by escaping with extra '\'.

	mdoc %T: use typographic quotes

	* tmac/doc.tmac-u: Changed \*[q] to \*[Lq] and \*[Rq]

	Citing Anthony J. Bentley:

	The below patch causes -mdoc to generate typographic quotes
	around a %T (reference title) instead of straight quotes.

	I also submitted similar diffs to mandoc and heirloom troff
	(which haven't been committed yet).  It would be nice for
	the major implementations not to differ here, and the change
	is trivial. 

	It's worth noting that groff's refer(1) already uses typographic
	quotes around %T with my -ms documents.

	mdoc \*[Lq], \*[Rq]: map to \[lq], \[rq] for all terminal
	devices

	* tmac/doc-nroff-u: .ds Lq \[lq], .ds Rq \[rq]

	If you use \[lq] and \[rq] directly in your document, the
	quotes already render nicely for all terminal devices:
	as U+201C and U+201D for devutf8 and as ASCII 0x22 (") for
	devascii and devlatin1.
	So it is not quite clear why doc-nroff should avoid
	\[lq] and \[rq] when resolving \[Lq] and \[Rq] for devascii
	and devlatin1. Quite to the contrary, many people seem to
	consider "``" and "''" ugly renderings because they look
	unbalanced.

	* tmac/doc.tmac-u: Simplify behaviour of .Bl -tag
	* tmac/groff_mdoc.7.man: Update documentation to the new
	behaviour of .Bl -tag

	If an mdoc(7) .Bl -tag macro lacks the -width argument, the
	body indentation is calculated separately for each child .It
	macro.  Neither the Heirloom nor the mandoc(1) implementation
	of the mdoc(7) language show such behaviour; both use a
	constant default width for the whole list in that case.

	Apart from doubts whether lists with variable indentation are
	typographically sound in the first place, support for variable
	widths in groff is so restricted that it's practically
	useless.  For each .It, the width will be the default width of
	whatever happens to be the leading macro after the .It, or of
	.No if .It is not followed by a macro.

	an implicite space is added between an unary operator and it's

	* contrib/mm/m.tmac: Disable macro misc@tag in case output
	  type is not HTML.

	This macro did cause unwanted space in case a MM macros .H
	had been followed immediately by .DS.

	(See also discussion at groff@gnu.org, thread starting at
	http://lists.gnu.org/archive/html/groff/2015-12/msg00033.html)

	gropdf was choking on -I flag passed by groff, now uses
	these directories to search for included pdfs.
	
	* src/devices/gropdf/gropdf.pl: Handle -I flag, avoid
	  unitialised values.
	
	* src/roff/groff/groff.1.man: Include 'X pdf: pdfpic'

	* src/roff/grog/subs.pl: fix comments

2015-09-03  Bernd Warken  <groff-bernd.warken-72@web.de>

	* tmac/troffrc: Add .mso for file `pdfpic.tmac'.

2015-08-28  Bertrand Garrigues  <bertrand.garrigues@laposte.net>

	* Makefile.am:
	- Use only the naming `.section.man' for all man.pages.
	- Replace `.man.n' by `.man' only, such that no `.n' is
	generated.
	- For example, the source `groff.7.man' is transformed into
	`groff.7' in the same directory and then is by installing just
	copied into one of the suitable installed man directory.

2015-08-27  Bernd Warken  <groff-bernd.warken-72@web.de>

	* tmac/pfdpic.tmac: Add tmac file for macro `PDFPIC'.

	number before the final `.man'.

	* all *.am: Include renaming.

	* Makefile.am: Reset `.man.n' by `.[157].man.n' with SUFFIXES
	`.[157].man .n'.

2015-08-20  Bernd Warken  <groff-bernd.warken-72@web.de>

	* Makefile.am: Fix definition of man[157]_MANS.

2015-08-13  Bernd Warken  <groff-bernd.warken-72@web.de>

	* all *.am: Correct Emacs mode `End:' instead of `End.'.

2015-08-09  Werner LEMBERG  <wl@gnu.org>

	Revert previous commit, since it doesn't work correctly yet.

2015-08-07  Bernd Warken  <groff-bernd.warken-72@web.de>

	Add section name to all man-page names.

	* Makefile.am: In `install-prefix-man' and `uninstall-prefix-man'

2015-07-01 Peter Bray <pdb_ml@yahoo.com.au>

	Fix Savannah bug #44784.

	Compatibility Mode rendering of groff manual pages

	* m4/groff.m4 (GROFF_WITH_COMPATIBILITY_WRAPPERS): New macro to
	implement 'configure' option
	'--with-compatibility-wrappers=<value>'.  With this option the
	user can control how groff compatibility wrappers for
	vendor-provided non-GNU macro sets are installed.

	* configure.ac: Use new macro GROFF_WITH_COMPATIBILITY_WRAPPERS.

	* Makefile.am: Define tmac_*_prefix if 'compatibility_wrappers' is
	set to 'yes'.

	* tmac/tmac.am: Use 'compatibility_wrappers' to control the
	installation:

	- If set to `no', the groff-provided macro set are installed in
	<prefix>/share/groff/<version>/tmac/ with the original macro set
	name.

	- If set to `yes', the groff-provided macro set are installed in
	<prefix>/share/groff/<version>/tmac/ with a prefix of
	$(tmac_prefix) (which is usually `g') and the generated
	compatibility wrappers are installed in
	<prefix>/lib/groff/site-tmac, with the original macro set name.

	- If set to `manual', the groff-provided macro set are installed
	in <prefix>/share/groff/<version>/tmac/ with the original macro
	set name and the generated compatibility wrappers are installed in
	<prefix>/lib/groff/site-tmac, with a name of
	<macro><wrapper_suffix> (which is usually `-os').

2015-06-17  Werner LEMBERG  <wl@gnu.org>

	* tmac/tty.tmac: Fix mapping of \[bu] character for -Tutf8.

	Problem reported by carsten.kunze@arcor.de.

2015-06-15  Deri James  <deri@chuzzlewit.myzen.co.uk>

	pdfmom should use $RT_SEP as path separator.

	* src/devices/gropdf/gropdf.am: Use @RT_SEP@ as path separator.

	* src/devices/gropdf/pdfmom.pl: As above but also fix typo in regex
	for grep.

2015-05-08  Eli Zaretskii  <eliz@gnu.org>

	[groff] Make relocation really work.

	See

	  https://lists.gnu.org/archive/html/groff/2015-05/msg00000.html

	* src/roff/groff/groff.cpp: Include `relocate.h'.
	(main): Use `relocatep'.

2015-05-03  Bertrand Garrigues  <bertrand.garrigues@laposte.net>

	Fix Savannah bug #44768 (Solaris 10 compatibility issues).

	* m4/groff.m4 (GROFF_DIFF_D): new macro to check if `diff' has
	option -D, and search for `gdiff' if not (new variable DIFF_PROG
	will contain the `diff' program to be used).

	* m4/groff.m4 (GROFF_HAVE_TEST_EF_OPTION): new macro to check if
	`test' supports the option -ef (created new variable
	HAVE_TEST_EF_OPTION).

	* m4/groff.m4 (GROFF_BASH): new macro to search for `bash' (new
	variable BASH_PROG will contain the full path to `bash' or
	`/bin/sh' if `bash' was not found).

	* configure.ac: use the 3 new macros defined in m4/groff.m4.

	* contrib/gdiffmk/gdiffmk.am: set HAVE_TEST_EF_OPTION, BASH_PROG,
	DIFF_PROG in the generated script `gdiffmk'.

	* contrib/gdiffmk/gdiffmk.sh:
	- Fix incorrect space after '!' in sed script regex.
	- `test -ef' is not portable: If `bash' is not available and the
	shell does not support `test -ef', the option to pass a third
	argument as the output file is disabled.
	- Report an error if `diff' does not support -D option.
	- GNU diff and Solaris diff support -D, but #ifndef / #endif are
	treated differently (GNU adds a '!' in the #endif): modify the
	regexs in the sed script accordingly.

2015-05-01  Werner LEMBERG  <wl@gnu.org>

	* tmac/tmac.am (TMACNORMALFILES): Add `zh.tmac'.

2015-04-30  Darcy SHEN  <sadhen1992@gmail.com>

	Fix Savannah bug #44941.

	* tmac/zh.tmac: New file to support basic Chinese (both simplified
	and traditional).

2015-04-22  Deri James  <deri@chuzzlewit.myzen.co.uk>

	Fix Savannah bug #44891.

	* src/devices/gropdf/gropdf.pl: If module Compress::Zlib is not
	available fall back to producing uncompressed PDF and output a
	warning.

2015-04-22  Bjarni Ingi Gislason  <bjarniig@rhi.hi.is>

	Fix Savannah bug #44894.

	* tmac/strip.sed: Add a `generated file' warning.

2015-04-21  Deri James  <deri@chuzzlewit.myzen.co.uk>

	Fix Savannah bug #44890.
	Patch by Peter Bray.

	* font/devpdf/devpdf.am: Don't use 'find -maxdepth'.

2015-03-07  Ingo Schwarze  <schwarze@openbsd.org>

	[mdoc] Fix Savannah bug #44733.

	Prevent mdoc(7) Bl with trailing -width or -offset from picking up
	old args.

	* tmac/doc.tmac-u (doc-do-Bl-args): When checking whether there is
	another argument to a Bl macro, do not inspect the argument list
	because it is never cleaned and may contain arguments from previous
	macro invocations.  Instead, inspect the argument count which is
	always up to date.

2015-04-10  Daiki Ueno  <ueno@gnu.org>

	Fix link error on NetBSD 6.

	Reported by carsten.kunze@arcor.de in:
	<https://lists.gnu.org/archive/html/groff/2015-04/msg00000.html>.
	The problem can also be reproduced if gl_cv_func_wcwidth_works=no
	is passed to configure.

	* src/preproc/grn/grn.am (grn_LDADD): Change the link order of
	libgroff.a and lib/libgnu.a according to dependency.
	* src/roff/troff/troff.am (troff_LDADD): Likewise.

2015-04-08  Werner LEMBERG  <wl@gnu.org>

	Fix Savannah bug #44767.
	Patch by Peter Bray.

	* src/roff/grog/grog.am (grog): Correctly substitute `grog_dir'.

2015-04-03  Werner LEMBERG  <wl@gnu.org>

	Fix Savannah bug #44708 (2/2).

2015-04-03  Werner LEMBERG  <wl@gnu.org>

	Fix Savannah bug #44708 (1/2).

	* tmac/andoc.tmac (reload_doc, reload_man): Don't use `de1',
	otherwise we can't manipulate the compatibility flag within the
	macro.

	* tmac/doc-common-u (Dt): Remove invalid leading whitespace.

2015-03-11  Deri James  <deri@chuzzlewit.myzen.co.uk>

	* src/devices/gropdf/gropdf.pl: Was not handling the final glyph
	correctly in the "standard" fonts which are not embedded. They
	actually have 257 glyphs (0-256) not 256 as I'd assumed, so the
	remappiing code needs to be applied for them as well as the
	embedded downloadable fonts.

2015-03-11  Deri James  <deri@chuzzlewit.myzen.co.uk>

	* src/devices/gropdf/gropdf.pl: Fix problem remappiing
	ellipsis (affects all glyphs > 255).

2015-03-07  Werner LEMBERG  <wl@gnu.org>

	* tmac/tmac.am (TMACSPECIALFILES): Removed.  No longer used.

2015-03-07  Ingo Schwarze  <schwarze@openbsd.org>

	* tmac/doc-common-u (Dd): Avoid warning `unbalanced .el request'.

2015-02-12  Werner LEMBERG  <wl@gnu.org>

	Minor fixes due to renaming `groff.texinfo' to `groff.texi'.

	* doc/doc.am (SUFFIXES): Update.
	* m4/groff.m4 (GROFF_MAKEINFO): Update.

2015-01-30  Bertrand Garrigues  <bertrand.garrigues@laposte.net>

	Automake migration and Gnulib integration.

	Gnulib:
	- Added gnulib as a git submodule.
	- Integrated bootstrap scripts from gnulib.
	- Gnulib m4 directory is now in `gnulib_m4', while Gnulib's .c
	files are located in `lib'.  `gnulib_m4' and `lib' are generated
	and distributed.

	Automake:
	- Removed Makefiles from the old build system.
	- Converted Makefile.in into Makefile.am.
	- Converted Makefile.sub files in all directories to a .am file.
	- Removed configure, src/include/config.hin (now generated).
	- Removed various helper scripts (config.guess, config.rpath...),
	now installed by bootstrap in `build-aux'.
	- Moved aclocal.m4 to acinclude.m4 (aclocal.m4 is now generated).
	- Makefile in non-recursive style.
	- Updated INSTALL.REPO (INSTALL is now a symlink to
	gnulib/doc/INSTALL, original INSTALL file moved to INSTALL.extra)
	- Added (empty) THANKS, AUTHORS files.
	- Added a document on the usage of automake in groff in
	doc/automake.pdf.

	Additional features:
	- Out-of-source build is supported.
	- Parallel build is possible (make -j).
	- Automatic targets from Automake: `make dist', `make distcheck'.
	- 'make check' is available for automatic testing, gdiffmk's test
	was plugged to this target.
	- Auto-detect if make has builtin variable `RM'.

2015-01-14  Ingo Schwarze  <schwarze@openbsd.org>

	Fix Savannah bug #43905.

	* src/libs/libgroff/glyphuni.cpp (glyph_to_unicode_list),
	* src/libs/libgroff/uniglyph.cpp (unicode_to_glyph_list): Remove
	double entries for `rk', `lk', `lt', `rt', `rb', and `lb'.

2014-12-16  Werner LEMBERG  <wl@gnu.org>

	Update Unicode-to-Unicode mapping to version 7.0.0.

	* src/libs/libgroff/make-uniuni: Update emitted copyright.

	* src/libs/libgroff/uniuni.cpp: Regenerated.

2014-11-29  Werner LEMBERG  <wl@gnu.org>

	Fix previous commit.

	We forgot to test whether the patch works if compiling from
	scratch...

	Problem reported by Bertrand Garrigues
	<bertrand.garrigues@laposte.net>.

	* src/include/lib.h (interpret_lf_args, normalize_for_lf): Move
	declarations to...
	* src/include/lf.h: This new file.

	* src/libs/libgroff/lf.cpp, src/preproc/pic/pic.h,
	src/preproc/preconv/preconv.cpp, src/preproc/refer/refer.h,
	src/preproc/soelim/soelim.cpp, src/preproc/tbl/table.h: Include
	`lf.h'.
	Make `lib.h' the first included header file.

	* src/preproc/eqn/eqn.h: Don't include `stringclass.h'.
	* src/preproc/eqn/main.cpp: Include `stringclass.h' and `lf.h'.

	* src/roff/groff/groff.cpp: Make `lib.h' the first included header
	file.

2014-11-10  Eli Zaretskii  <eliz@gnu.org>

	Improve native Windows port.

	This patch fixes two issues.

	  . Handle backslashes in `.lf' arguments for MSDOS and Windows.
	  . Fix file name quoting for the groff pipeline.

	* src/preproc/soelim/soelim.cpp (do_file):
	* src/preproc/refer/refer.cpp (do_file):
	* src/preproc/preconv/preconv.cpp (do_file):
	* src/preproc/pic/main.cpp (do_file):

	* src/preproc/eqn/eqn.h:
	* src/preproc/pic/pic.h:
	* src/preproc/refer/refer.h:
	* src/preproc/tbl/table.h: Include stringclass.h before lib.h.

	* src/libs/libgroff/lf.cpp (normalize_for_lf): New function.

	* src/roff/groff/groff.cpp: Include stringclass.h before lib.h.
	(append_arg_to_string) [_WIN32 && !__CYGWIN__]: Use only "..." for
	quoting in native Windows builds.

2014-11-18  Deri James  <deri@chuzzlewit.myzen.co.uk>

	My commit '3fe78135c9fe666dadffde2a822b0535d8db6feb' introduced
	problem in subroutine `TextWid'.  Octal char `\nnn' returns width of
	4 char string rather than width of single character.

	* src/devices/gropdf/gropdf.pl: Change `TextWid' to recognise octal
	escaped characters (\nnn).

2014-11-07  Deri James  <deri@chuzzlewit.myzen.co.uk>

	See bug #43555.

	* src/devices/gropdf/gropdf.pl: Correct Date Format.

2014-11-04  Werner LEMBERG  <wl@gnu.org>

	* src/libs/gnulib/*: Regenerate autotool files.

2014-11-04  Werner LEMBERG  <wl@gnu.org>

Version 1.22.3 released
=======================

	* NEWS, README, doc/webpage.ms: Updated.

	* doc/texinfo.tex: Updated from `texinfo' repository.

2014-10-29  Bertrand Garrigues  <bertrand.garrigues@laposte.net>

	* Makefile.in (OTHERDIRS): Mention `afmtodit' first.

	Otherwise, some fonts in `devpdf' (`U-*') are not built.

2014-10-26  Eli Zaretskii  <eliz@gnu.org>
	    Werner LEMBERG  <wl@gnu.org>

	Add Windows `.cmd' wrapper files.

	* arch/mingw/*: New files, provided by Eli.

	* Makefile.in (make_winscripts, make_install_winscripts,
	make_uninstall_winscripts): New target variables.
	(MDEFINES): Add them.
	(OTHERDIRS): Add `arch/mingw'.

	* m4/groff.m4 (GROFF_CMD_FILES): New macro
	* configure.ac: Call it.
	* configure: Regenerated.

2014-10-23  Bertrand Garrigues  <bertrand.garrigues@laposte.net>

	Fix `install' and `uninstall' issues.

	* contrib/chem/Makefile.sub (install_data): Fix build with option
	--with-doc=no passed to configure (target `install_examples'
	should not be executed).

	* contrib/chem/Makefile.sub (uninstall_sub):  `uninstall' failed
	if directories to be removed were not present.

	* contrib/gpinyin/Makefile.sub (uninstall_sub): Ditto.

	* contrib/hdtbl/Makefile.sub (GENFILES): generated files should
	depend on the creation of the `examples' directory.

2014-10-23  Daiki Ueno  <ueno@gnu.org>

	* m4/iconv.m4: Really avoid false detection of non-working iconv.

2014-10-21  Daiki Ueno  <ueno@gnu.org>

	iconv: avoid false detection of non-working iconv

	The INBUF/OUTBUF arguments of iconv can be either 'const char **'
	or 'char **'.  If CC is g++, the difference causes a compile error
	and thus leads to a false detection of non-working iconv.
	Reported by Eli Zaretskii and Werner LEMBERG in:
	<https://lists.gnu.org/archive/html/bug-gnulib/2014-10/msg00023.html>.

	* m4/iconv.m4 (AM_ICONV_LINK): Try all possible argument types of
	iconv.  Bump serial number.

2014-10-20  Werner LEMBERG  <wl@gnu.org>

	* src/libs/gnulib/lib/wctype.in.h: Include `config.h'.

	Problem reported by Eli Zaretskii <eliz@gnu.org>.

	This is a temporary hack to make groff compile with MinGW.  After
	the switch to an automake infrastructure, together with proper use
	of `gnulib', we can safely replace the patched file with a standard
	version.

2014-10-19  Doug McIlroy  <doug@cs.dartmouth.edu>

	Fix Savannah bug #42151.

	* src/preproc/eqn/lex.cpp (file_input::read_line): Handle CR/LF.
	* src/preproc/pic/pic.cpp (file_input::read_line): Ditto.

2014-10-18  Werner LEMBERG  <wl@gnu.org>

	[mdoc] Add Darwin version string for OS X 10.10.

	* tmac/doc-common (doc-operating-system-Darwin-14.0.0): New string.

	* tmac/groff_mdoc.man: Updated.

2014-10-15  Werner LEMBERG  <wl@gnu.org>

	* doc/webpage.ms: Remove obsolete references to tarballs and diffs.

	Reported by Dave Kemper <saint.snit@gmail.com>.

2014-10-15  Colin Watson  <cjwatson@debian.org>

	Always distribute the parts of groff that require X11.

	* Makefile.in (ALLLIBDIRS): Clone from `LIBDIRS', but include
	src/devices/libxutil unconditionally.
	(ALLPROGDIRS): Clone from `PROGDIRS', but include
	src/devices/xditview and src/utils/xtotroff unconditionally.
	(DISTDIRS): Use `ALLLIBDIRS' and `ALLPROGDIRS' rather than `LIBDIRS'
	and `PROGDIRS'.

2014-10-14  Keith Marshall  <keith.d.marshall@ntlworld.com>

	Minor update to NEWS for pdfroff.

	* NEWS (pdfroff): Note use of PHASE register, and not pdf:href.map,
	to choose when to emit toc_relocation control record.

2014-10-13  Keith Marshall  <keith.d.marshall@ntlworld.com>

	For pdfroff, deduce "--no-toc-relocation" from input stream.

	* NEWS: Add notification; document the effect of changes, as recorded
	in contrib/pdfmark/ChangeLog.

2014-10-12  Ingo Schwarze  <schwarze@openbsd.org>

	[mdoc] Support `Mdocdate' CVS keyword substitution.
	This fixes Savannah bug #42968.

	This feature is used for OpenBSD manuals.

	* tmac/doc-common (Dd): Handle `$Mdocdate:' argument.

	* tmac/groff_mdoc.man: Document it.

2014-10-12  Ingo Schwarze  <schwarze@openbsd.org>

	This fixes Savannah bug #42971.

	* tmac/doc-syms: Add corresponding version strings.

	* tmac/groff_mdoc.man: Synchronize.

2014-10-12  Ingo Schwarze  <schwarze@openbsd.org>

	* tmac/doc-common: Update NetBSD, OpenBSD, FreeBSD, and DragonFly
	version strings.

	* tmac/groff_mdoc.man: Synchronize.

2014-10-12  Werner LEMBERG  <wl@gnu.org>

	* doc/Makefile.in: Use `LC_ALL' in addition to `LANG'.
	Suggested by Steffen.

2014-10-12  Werner LEMBERG  <wl@gnu.org>

	* doc/groff.texinfo: Make PDF version compilable with makeinfo 5.x.

	makeinfo 5.x handles macro expansion better, which changes the way
	how an \LE macro (for a less-than sign) has to be defined.  However,
	since we can't be sure that the latest version of `texinfo.tex' gets
	used with makeinfo 5.x only, we would have to support both 4.x and
	5.x.  No idea whether this is possible at all...  For this reason,
	we now simply use @value directly instead of wrapping it into a
	macro, avoiding any issues.

2014-10-12  Werner LEMBERG  <wl@gnu.org>

	[doc] Protect against picky `sed' programs.
	Problem reported by Axel Kielhorn <tex@axelkielhorn.de>.

	* doc/Makefile.in (GROFF_BIN_PATH, GROFF): Add `LANG=' to avoid
	interpretation of non-ASCII characters by sed.

2014-10-12  Michail Vidiassov  <master@iaas.msu.ru>

	* tmac/doc-common: Add new Darwin versions.

2014-10-12  Werner LEMBERG  <wl@gnu.org>

	* doc/groff.texinfo: s/which/that/ where apropriate.

2014-10-12  Werner LEMBERG  <wl@gnu.org>

	* doc/groff.texinfo: Various minor fixes.

	Most of those glitches have been found by comparing the info output
	from makeinfo 4.13 and the current SVN development version (of
	makeinfo).

2014-10-12  Werner LEMBERG  <wl@gnu.org>

	* doc/groff.texinfo: Improve indexing.

	Change @DefXXXItem and @DefXXXListEnd macros to not insert an index
	entry.  New macro variants with a trailing `x' (like `@DefreqItemx')
	can override this.

	Update macro calls where necessary.

2014-10-12  Werner LEMBERG  <wl@gnu.org>

	[doc] Improve call to generation of `groff.pdf'.
	Problem reported by Axel Kielhorn <tex@axelkielhorn.de>.

	Since `groff.texinfo' contains latin-1 characters, some sed
	implementations (like the one used on Mac OS 10.8) fail if called
	with the wrong locale.  Basically, this is a `texi2dvi' bug, but we
	can set `LANG' by ourselves to improve the situation.

	* doc/Makefile.in (.texinfo.dvi, .texinfo.pdf): Set `LANG'
	environment variable to empty string.

2014-10-12  Werner LEMBERG  <wl@gnu.org>

	[doc] Correctly handle `MAKEINFO' environment variable.
	Bug introduced in commit from 2014-03-29.

	* m4/groff.m4 (GROFF_MAKEINFO): Don't set MAKEINFO to empty string
	before actually testing it.

	* configure: Regenerated.

2014-10-11  Bertrand Garrigues  <bertrand.garrigues@laposte.net>

	Fix an issue on `make dist'.

	In order to make the tarball, `make dist' copies src/libs/gnulib
	directories into the `tmp' directory without the `.deps'
	directories, causing the failure of `make distclean' in
	tmp/src/libs/gnulib.  Forcing a call to `config.status' recreates
	the `.deps' directories.

	* Makefile.in (dist): For gnulib, call `config.status' before `make
	distclean'.

2014-10-11  Bernd Warken  <groff-bernd.warken-72@web.de>

	* src/roff/grog/*.pl: Remove call from `IPC', use normal system
	`instead'.

2014-10-11  Guillem Jover  <guillem@hadrons.org>

	Add support for various BSD versions.

	* tmac/doc-common: Add new FreeBSD and DragonFly versions.

2014-10-11  Keith Marshall  <keith.d.marshall@ntlworld.com>

	Refactor .psbb request handling code.

	* src/roff/troff/input.cpp (do_ps_file): Reimplement it, using...
	(psbb_locator): ...this new locally declared and implemented class;
	its constructor replaces all `do_ps_file()' capability, delegating
	to other class methods, as appropriate.
	(assign_registers): Encapsulate it, as a `psbb_locator' method.
	(ps_get_line): Likewise, also renaming it to become...
	(get_line): ...this class method; its internally defined `lastc'
	static variable also becomes a non-static class member variable.
	(PSBB_RANGE_IS_BAD, PSBB_RANGE_IS_SET, PSBB_RANGE_AT_END): New
	manifest constants; define them.  They are now used by...
	(parse_bounding_box): ...this function, now also encapsulated as
	a `psbb_locator' class method, to convey parsing status.
	(bounding_box): Struct obsoleted by `psbb_locator'; delete it.
	(ps_bbox_request): Delegate to `psbb_locator'.

2014-10-11  Werner LEMBERG  <wl@gnu.org>

	Various clean-ups.

	* NEWS: More updates.

	* REVISION: Set to 3.

	* doc/groff.texinfo: Update version and year.

	* configure: Regenerated.

	* src/roff/groff/groff.cpp (main) <'v'>: Update copyright year.

2014-10-11  Werner LEMBERG  <wl@gnu.org>

	* NEWS, MANIFEST: Updated.

2014-10-11  Werner LEMBERG  <wl@gnu.org>

	* Makefile.in (OTHERDIRS, NOMAKEDIRS): Remove `ideal' references.

2014-10-10  Bernd Warken  <groff-bernd.warken-72@web.de>

	* contrib/gideal: Temporarily remove this directory, because the
	documentation and the preprocessor are not yet finished for
	groff-1.2.23.

2014-10-10  Werner LEMBERG  <wl@gnu.org>

	* Makefile.in (dist): Clean up `src/libs/gnulib'.

2014-10-10  Werner LEMBERG  <wl@gnu.org>

	* doc/webpage.ms: Updates.

	The README and NEWS sections are not yet synchronized, though.

2014-10-09  Ingo Schwarze  <schwarze@openbsd.org>

	* Makefile.in: Let `clean' and `distclean' descend into gnulib.

	This fixes Savannah bug #42970.

2014-10-02  Bertrand Garrigues  <bertrand.garrigues@laposte.net>

	Set default X11 resources dir to `$prefix/lib/X11/app-defaults'.

	Previously, X11 resources for gxditview were installed in
	`/usr/X11/lib/X11/app-defaults', no matter which prefix was set.

	Now, gxditview resources are installed in
	`appresdir=$prefix/lib/X11/app-defaults'.  If `appresdir' is not a
	standard X11 resource directory, the environment variable
	`XFILESEARCHPATH' should be set to this path.

	The behaviour of `--with-appresdir' is unchanged: This option can
	still be used to set `appresdir', and its value will not be modified
	by the prefix.

	* m4/groff.m4 (GROFF_APPRESDIR_DEFAULT): Implement new behaviour.
	Fix detection app-defaults location on the system.
	(GROFF_APPRESDIR_CHECK): Updated.

	* configure.ac: Improve output of configuration.
	* configure: Regenerated.

	* NEWS: Mention it.

2014-09-27  Werner LEMBERG  <wl@gnu.org>

	Set `transparent' flag for `\[cq].
	Problem reported by Dave Kemper <saint.snit@gmail.com>.

	* src/roff/troff/input.cpp (init_charset_table): Do it.

	* doc/groff.texinfo (Sentences, Using Symbols), man/groff_diff.man:
	Document it.

2014-09-25  Bernd Warken  <groff-bernd.warken-72@web.de>

	* src/roff/grog/*.pl: Program more reasonable subs (functions).
	Repair details in many places.

2014-09-24  Keith Marshall  <keith.d.marshall@ntlworld.com>

	Refactor psbb line input function; avoid a buffer overrun.

	* src/roff/troff/input.cpp (ps_get_line): Declare it as `static'.
	Refactor, to avoid the overhead of character look-ahead and push-back
	on CR stream input.  Add new `dscopt' parameter, in place of internal
	`err' variable; update all call references, passing value of...
	(DSC_LINE_MAX_ENFORCE): ...this new manifest constant; define it.
	(DSC_LINE_MAX_IGNORED): Likewise; currently unused, but intended for
	future use as an alternative to `DSC_LINE_MAX_ENFORCE'.
	(DSC_LINE_MAX_CHECKED): New manifest constant; used internally only.
	(PS_LINE_MAX): Manifest constant, renamed for notional consistency...
	(DSC_LINE_MAX): ...to this; defined value remains as 255.
	(do_ps_file): Increase stack allocation for `buf' char array; former
	allocation of PS_LINE_MAX (now DSC_LINE_MAX) bytes exposed a potential
	buffer overrun, after reading DSC_LINE_MAX bytes; two additional bytes
	are required, to accommodate a terminating LF and NUL.  Add `dscopt'
	parameter, with value `DSC_LINE_MAX_ENFORCE', in each of three calls
	to `ps_get_line()'.

2014-09-20  Bernd Warken  <groff-bernd.warken-72@web.de>

	* src/roff/groff/Makefile.sub: Remove too much deleting while
	running `make'.

2014-09-20  Bernd Warken  <groff-bernd.warken-72@web.de>

	* `Makefile.sub' in the whole groff source tree: Add $(RM) and
	change all `rm -f'.  Add directory test before `rmdir'.

2014-09-20  Bernd Warken  <groff-bernd.warken-72@web.de>

	* Man-pages (*.man) in the whole groff source tree: Improve
	documents by adding \[co], \[cq], \[aq] instead of ` or ' and use
	also \[co] as long as it makes sense.  Remove \[en] in the years
	date in order to allow the automatic license year increasing.

2014-06-03  James Cloos  <cloos@jhcloos.com>

	work with the `pdf' device.

2014-06-02  Bernd Warken  <groff-bernd.warken-72@web.de>

	* src/roff/grog/grog.pl: The `grog' version of yesterday has many

	* src/roff/grog/grog.man: make generated options more readable.

2014-05-26  Bernd Warken  <groff-bernd.warken-72@web.de>

	* src/roff/grog/grog.pl: Add detection of `.\" [eprt]' as first
	line to `grog'.  Change usage of `$Sp' to reasonable efforts in
	`groff'.

	* src/roff/grog/grog.man, man/groff_char.man: Add website for
	license text, not only the postal address.

2014-04-03  Steffen Nurpmeso  <sdaoden@yandex.com>

	* */Makefile.*: Path quoting fixes, whitespace, formatting.

	Remove many quotes (and introduce a few as additional guards)
	since groff's build system is generally not set up to properly
	handle paths that need quoting.

2014-04-03  Steffen Nurpmeso  <sdaoden@yandex.com>

	* Makefile.comm (extraclean): Don't delete `old'.

	The rule calling `rm -f' was originally thought to remove private,
	temporary files.  However, we now have a subdirectory called `old'
	in `fonts/devps' that may not be removed, and trying so now causes
	an error because we no longer ignore the returned error code of
	`rm'.

2014-04-03  Steffen Nurpmeso  <sdaoden@yandex.com>

	* Makefile.in (OTHERDIRS): Fix directory order.

	This has been accidentally broken in commit 51476bee from

	Add fine-tuning of doc generation to `configure'.

	`--with-doc' and its new arguments.  It sets
	`docadd_{html,info,other,pdf,examples}' and exports
	`make{_,_install_,_uninstall_}{otherdoc,examples}'.
	(GROFF_MAKEINFO): Extended to export
	`make{_,_install_,_uninstall_}infodoc'.
	(GROFF_HTML_PROGRAMS): Extended to export

	(GROFF_PDFDOC_PROGRAMS): Extended to export

	(GROFF_INSTALL_INFO): Guard test with `docadd_info'.

	* configure.ac: Use GROFF_DOC_CHECK.
	* Makefile.in: Updated.

	* doc/Makefile.sub: Handle examples separately, controlled by
	$(make{_,_install_,_uninstall_}examples).

2014-03-27  Bjarni Ingi Gislason  <bjarniig@rhi.hi.is>

	* tmac/www.tmac (TAG): Define register `PN'.

2014-03-27  Bjarni Ingi Gislason  <bjarniig@rhi.hi.is>

2014-03-16  Werner LEMBERG  <wl@gnu.org>

2014-03-14  Werner LEMBERG  <wl@gnu.org>

	Contributed by Grégoire Babey <gibux@gmx.ch>.

	* doc/meintro_fr.me: New file.
	* LICENSES, doc/Makefile.sub: Updated.

2014-03-13  Ingo Schwarze  <schwarze@openbsd.org> (tiny change)

	man: Correctly reset margins.

	See

	http://lists.gnu.org/archive/html/groff/2013-11/msg00026.html

	for more.

	* tmac/an-old.tmac (set-an-margin): Whenever (re)setting
	`\n[an-level]' to 1 (which happens when encountering `.TH', `.SH',
	and `.SS') make sure to also (re)set `\n[an-saved-margin1]' and
	`\n[an-saved-prevailing-indent1]' to a sane value such that an
	immediate `.RE' cannot wreak havoc.
	(TH, SH, SS): Updated.

2014-03-11  Ingo Schwarze  <schwarze@openbsd.org> (tiny change)

	* Makefile.in: Do not forget to install gropdf manuals.

	This got broken in 290eaaac6cfc33856cd683838accc72ccf3e5a84:
	src/devices/gropdf was split out of OTHERDIRS into SHPROGDIRS, and
	consequently, Makefile.man was no longer used there.  Note that
	Makefile.dev is *not* needed, even though it's below /devices/.

2014-03-11  Ingo Schwarze  <schwarze@openbsd.org> (tiny change)

	* src/roff/groff/Makefile.sub: POSIX conformance.

	- POSIX says that the meaning of the make(1) `$<' macro shall be
	   unspecified except in inference rules.  Consequently, use `$?'
	   for portability.

	   That's safe because the rules have only one prerequisite and
	   are not `.PHONY', so `$?' will always expand to one item.

	- While here, clean up two instances of superfluous use of cat(1).

2014-03-11  Ingo Schwarze  <schwarze@openbsd.org> (tiny change)

	* Makefile.in (dist): Improve.

	- Bugfix: Do not error out if one of the DISTDIRS
	   contains a subdirectory.
	- Make debugging easier by splitting the huge "cd tmp; ...; ..."
	   command sequence into several independent shell commands,
	   such that one can see which command actually fails.

2014-03-06  Deri James  <deri@chuzzlewit.myzen.co.uk>

	Missing RE escape in grep.

	* src/devices/gropdf/pdfmom.pl: Escape '\' dot in grep RE.

2014-02-26  Bernd Warken  <groff-bernd.warken-72@web.de>

	* src/roff/grog/grog.pl: Add detection of `gperl' to `grog'.

2014-02-25  Bernd Warken  <groff-bernd.warken-72@web.de>

	* contrib/gperl: New preprocessor for Perl parts in groff files.

2014-02-15  Ingo Schwarze  <schwarze@openbsd.org>

	* tmac/groff_mdoc.man: Improve the manual page template.

	 - Add the EXIT STATUS section.  It is widely used in at least
	   NetBSD, FreeBSD, OpenBSD, and DragonFly manuals.
	 - Recommend the DIAGNOSTICS section for section 4 manuals.  Such
	   usage is very widespread, in particular for kernel printf
	   messages emitted by device drivers.
	 - Do not recommend the DIAGNOSTICS section for command return
	   values to the shell any longer.  While such usage historically
	   existed, it does not seem common nowadays, and in any case, using
	   the now well-established EXIT STATUS section seems preferable to
	   me.
	 - Mention the possibility to use ERRORS for section 4 manuals.
	   While most section 4 manuals have a DIAGNOSTICS section, only
	   some will need an ERRORS section, but these cases aren't exactly
	   rare, either.  Quite some device driver manuals explain how to
	   use the device using system calls like ioctl(2), open(2), read(2)
	   or write(2), in which case the ERRORS section is the natural
	   place to explain which errno values the driver may set during
	   such system calls.
	 - Mentioning signal handling as a content of the ERRORS section
	   seems redundant, it is already covered by talking about the
	   errno.  The case of errno == EINTR should be handled just like
	   all other errno cases.  For an example showing that there is no
	   need to single out error handling in any way, please look at a
	   typical read(2) manual page.
	 - Mention the CAVEATS section.  It first appeared in the 4.2BSD
	   execve(2) manual in 1983, was already used by several manuals by
	   the time of 4.4BSD-Lite2 in 1995, and is in whidespread use
	   today, not just in BSD base system manuals, but for example in
	   Perl manuals as well.

2014-02-14  Bernd Warken  <groff-bernd.warken-72@web.de>

	* src/roff/grog/grog.pl: Add detection of glilypond-parts in groff
	files.  For example `grog example.groff' from the glilypond source
	gets `glilypond example.groff | groff'.

2014-02-12  Bernd Warken  <groff-bernd.warken-72@web.de>

	* src/roff/grog/grog.pl: With the former bugfix of 2014-02-12,
	it's now possible to run `grog meref.me' etc., which wasn't

	* groff/src/roff/groff/groff.cpp: add groff option `-G' to the
	documentation in `synopsis()'.

2013-12-06  Mike Frysinger  <vapier@gentoo.org>

	Fix parallel build with gropdf and mom examples.

	The `contrib/mom/examples/' directory uses the helper script from
	`src/devices/gropdf/'.  Currently though, parallel builds might fail
	like so:

	  ...
	  make[2]: Entering directory `.../groff-1.22.2/contrib/mom'
	  <groff command> examples/letter.mom >examples/letter.pdf
	  <groff command> examples/mom-pdf.mom >examples/mom-pdf.pdf
	  /bin/sh: .../groff-1.22.2/src/devices/gropdf/pdfmom: No such file or directory
	  make[2]: *** [examples/letter.pdf] Error 127
	  /bin/sh: .../groff-1.22.2/src/devices/gropdf/pdfmom: No such file or directory
	  make[2]: *** [examples/mom-pdf.pdf] Error 127
	  make[2]: Leaving directory `.../groff-1.22.2/contrib/mom'
	  make[1]: *** [contrib/mom] Error 2
	  ...
	  make[2]: Entering directory `.../groff-1.22.2/src/devices/gropdf'
	  sed -f .../groff-1.22.2/arch/misc/shdeps.sed \
	      -e "s|@VERSION@|1.22.2|" \
	      -e "s|@PERLPATH@|/usr/bin/perl|" ./pdfmom.pl >pdfmom

	The top level makefile tries to account for this in general with
	OTHERDIRS, but looks like `src/devices/gropdf/' was added to this
	variable (which holds `contrib/mom/' too) because gropdf installs a
	shell script, and the other prog vars require it to be a dir of
	things to compile.

	  URL: http://crbug.com/324116
	  URL: https://bugs.gentoo.org/487276

	* Makefile.in (SHPROGDIRS): Declare.

	no longer needed.

	* src/roff/groff/Makefile.sub: Get the `groff' options from the
	use of `getopt...' in `groff.cpp' using `$(EGREP)' and `sed'.
	Store this information in a new file `groff_options.txt', which
	is copied to `groff libdir' during the installation.

2013-04-26  Werner LEMBERG  <wl@gnu.org>

	Various minor fixes.

	* INSTALL.gen: Take the newest version from the `gnulib'

2013-04-26  Bernd Warken  <groff-bernd.warken-72@web.de>

	* src/roff/groff/read_groff_options.pl: Reads `groff' options
	from `groff.cpp' and writes them into the file `groff_options.info'.

	* src/roff/groff/Makefile.sub: Have the generated file

	* Makefile.in: Add `$(PERLVERSION)'.

	* aclocal.m4: Run `autoreconf -I m4' (this includes
	`aclocal -I m4').  This creates a suitable `aclocal.m4'.  Remove
	generated subdirectory `autom4te.cache'.

	* src/roff/grog/Makefile.sub: Correct `sed' command.  Use `tabs'
	that are needed by `GNU make'.

	to `$PERL', which has the same content.  But `$PERL' suits to
	`AX_PROG_PERL_VERSION' in m4 macro `GROFF_PERL' in `m4/groff.m4'.

	* README, INSTALL, INSTALL.gen, MANIFEST: Add documentation in the
	top directory about some parts of `autotools' and `glilypond'.

2013-04-15  Bernd Warken  <groff-bernd.warken-72@web.de>

	* configure.ac: Add information of the macro `GROFF_PERL'.

	* Makefile.in: Add definitions of the macro variables and their
	`@...@' counterparts.

	Run `autoreconf -I m4'.

2013-04-15  Bernd Warken  <groff-bernd.warken-72@web.de>
2013-04-15  Werner LEMBERG  <wl@gnu.org>
2013-04-15  Ralph Carderoy  <ralph@inputplus.co.uk>

	Add Perl test to configuration.  During the run of `configure' the
	program is broken with error when there is no `Perl' or the `perl'
	program is too old.

	* m4/groff.m4: Add macro `GROFF_PERL' that tests the availability
	of the `perl' program and tests wether this has a version of at
	most `v5.6.1'.  Define variables $PERL and $PERLPATH for the full
	name of the `perl' program and $PERLVERSION as the lest version.

2013-04-13  Keith Marshall  <keithmarshall@users.sourceforge.net>

	Avoid consideration of autotool cache for CVS inclusion.

	* .cvsignore (autom4te.cache): Add reference.

	groff CVS and removed it again after an email-discussion.

2013-04-12  Bernd Warken  <groff-bernd.warken-72@web.de>

	* `grog': Remove the shell version of `grog'.  Now there is only
	Perl version.

	* src/roff/grog/perl.sh: Remove this file.

	* src/roff/grog/Makefile.sub: This file handles the removement of
	the shell version.

	* src/roff/grog/perl_test.pl: New file for testing the available
	Perl version in the system to be installed into.  This file will
	be installed into the grog lib-directory.

2013-04-12  Bernd Warken  <groff-bernd.warken-72@web.de>

	* `grog': In the following, the file `grog.pl' will be split.  For
	the coming files, a lib-directory is needed for storage.

	* m4/groff.m4, configure.ac: Add libdir information for `grog'.

	* Makefile.in: Add @grog_dir@.

	Run `autoconf'.

	`grog' has now a lib-directory at `$prefix/lib/groff/grog'.

2013-04-11  Bernd Warken  <groff-bernd.warken-72@web.de>

	* contrib/groffer/: There is a free `git' package containing all
	old `groffer' versions `v0.*' and `v1.*'.  The new versions
	`groffer 2.*' will actually not be included.  This package can be
	got at:

	$ git clone git@github.com:RUNOFF/groffer.git

2013-04-11  Bernd Warken  <groff-bernd.warken-72@web.de>

	* contrib/glilypond/: There is a free `git' package containing all
	old versions of the former name `groff_lilypond v0.*'.  They work
	with `lilypond' parts in `roff' files, but were not installed.
	This package can be got at:

	$ git clone git@github.com:RUNOFF/groff_lilypond.git

	The new versions `glilypond v1.*' are not included there.

2013-04-11  Bernd Warken  <groff-bernd.warken-72@web.de>

	* man/roff.man: For roff(7), add information about the free git
	package RUNOFF.git with documentation about historical RUNOFF and
	the available files written in the classical RUNOFF language..

2013-03-29  Bernd Warken  <groff-bernd.warken-72@web.de>

	Rename `groff_lilypond' to `glilypond'.  So remove the former
	source directory `<groff_src_dir>/contrib/lilypond' and newly
	install `<groff_src_dir>/contrib/glilypond', which now has many
	files.  The new version starts at `v1.0'.

	* m4/groff.m4, configure.ac: Add libdir information for
	`glilypond'.

	* Makefile.in: Add `<groff_src_dir>/contrib/glilypond'.

	Run `autoconf'.

	`glilypond' can now be installed to the system.

2013-03-17  Ingo Schwarze  <schwarze@openbsd.org>

	* font/devpdf/Makefile.sub: Build system fixes.

	(GROFF_FONT_FILES): Avoid installing Makefile.sub.orig when it's
	around.
	(install): Create $(DESTDIR)$(fontsubdir)/util when missing.

2013-03-05  Werner LEMBERG  <wl@gnu.org>

	* doc/groff.texinfo: Improve documentation of `\s'.

	Reported by Jim Avera <james_avera@yahoo.com>.

2013-02-16  Werner LEMBERG  <wl@gnu.org>

	* doc/groff.texinfo: Improve documentation of `.substring'.

	* doc/groff.texinfo: Fix if-else example.

2013-02-10  Werner LEMBERG  <wl@gnu.org>

	[grops] Make binary `%%BeginData' work; support `fontset' resource.

	* src/devices/grops/psrm.cpp (resource_table): Add `fontset'.

	(resource_manager::read_resource_arg): Do a case insensitive
	comparison.  The PostScript Reference Manual gives the following
	example for a CFF resource (example 5.7):

	%!PS-Adobe-3.0 Resource-FontSet
	%%DocumentNeedResources: ProcSet (FontSetInit)
	%%Title: (FontSet/CFFRoman27)
	%%Version: 1.000
	%%EndComments
	%%IncludeResource: ProcSet (FontSetInit)
	%%BeginResource: FontSet (CFFRoman27)
	/FontSetInit /ProcSet findresource begin
	%%BeginData: 622532 Binary Bytes
	/CFFRoman27 622503 StartData
	... 622,503 bytes of binary data ...
	%%EndData
	%%EndResource
	%%EOF

	Note the `ProcSet' and `FontSet' keywords.  While the old DSC
	(Document Structure Convention) documentation doesn't cover
	`FontSet' at all (the DSC documentation predates the invention of
	CFF), it describes only `procset' (all letters downcase), and it
	also says that the DSC parser works in a case sensitive manner.

	In other words, `ProcSet' is not valid according to the DSC
	documentation, only `procset' is.  So much about today's validity
	of DSC...  This patch adapts grops's code to the PostScript
	reality.

	(resource_manager::do_begin_data): Fix typo (present since the
	beginning) which prevented correct handling of binary data.

	* src/devices/grops/ps.h (resource_type): Add RESOURCE_FONTSET.

2013-02-10  Bernd Warken  <groff-bernd.warken-72@web.de>

	* contrib/lilypond: New files for adding lilypond parts into groff

	(MOSTLYCLEANADD): Add `BuildFoundries'.
	* src/devices/gropdf/Makefile.sub (MOSTLYCLEANADD): Add `pdfmom'.

2013-01-24  Bernd Warken  <groff-bernd.warken-72@web.de>

	* Add a shell command to 'MANIFEST' that displays all man source
	files and their section.

2013-01-22  Bernd Warken  <groff-bernd.warken-72@web.de>

	* Add email address in all files having the name.

2013-01-14  Deri James  <deri@chuzzlewit.myzen.co.uk>

	* src/devices/gropdf/gropdf.pl (do_x, do_p, do_s, Set_LWidth): The
	grops driver defaults to round linecaps and linejoins, gropdf
	incorrectly used butt caps and miter joins.

	(Since the MOM package expects to use butt caps and miter joins
	(emitting the necessary postscript code to change the caps and
	joins), gropdf now parses the same postscript commands.)

	* src/devices/gropdf/gropdf.man: Document the handling of linecaps
	and linejoins.

	* tmac/pdf.tmac (pdfbookmark): Fix bug where the current
	PDFOUTLINE.FOLDLEVEL may not be honoured if warnings of the type

	macro warning: adjusted level n bookmark; should be <= n

	Added copyright and mention debt owed to Keith Marshall for
	original `pdfmark.tmac', upon which `pdf.tmac' is largely based.

	* font/devpdf/Foundry.in, font/devpdf/util/BuildFoundries.pl
	(LocateFile): The font for EURO had the wrong entry in the
	`download' file (it pointed to The font in the build directory,
	which is wrong).  It has always been permissable to include a path
	along with the font name in the Foundry file, but until now the
	font had to exist to be valid.  It is now permitted to start the
	path with an asterisk which tells BuildFoundry to use the
	path/filename in the download file without checking if the font
	exists.  This allows the font to be found in `../devps' even
	though it is not there during the build (if source and build are
	different), but will be there after the install.

2013-01-13  Werner LEMBERG  <wl@gnu.org>

	[eqn] Fix display of matrices in nroff output.

	Problem reported by Andy Spencer <andy753421@gmail.com>.

	* src/preproc/eqn/pile.cpp (pile_box::compute_metrics,
	matrix_box::compute_metrics): Fix rounding.

2013-01-07  Deri James  <deri@chuzzlewit.myzen.co.uk>

	* tmac/europs.tmac: Protect against missing fonts.

2013-01-07  Deri James  <deri@chuzzlewit.myzen.co.uk>

	* font/devpdf/util/BuildFoundries.pl (LoadFoundry): Improve
	warning.

2013-01-07  Werner LEMBERG  <wl@gnu.org>

	[tbl] Allow characters #, `, and ' as eqn delimiters.

	While problems ` and ' have been unintentionally introduced rather
	recently, the limitation regarding # was there from the beginning.

	At the same time, fix a small bug causing `.lf' requests not
	starting a line.

	* src/preproc/tbl/table.cpp (table::init_output)
	(table::compute_expand_width, table::compute_separation_factor)
	(table::define_bottom_macro, table::do_bottom): Temporarily switch
	off eqn delimiters, wrapping the code into a `.ig' block.  This
	uses the new functionality just added to eqn.

	* src/preproc/eqn/eqn.man, src/preproc/tbl/tbl.man: Updated.

2013-01-06  Werner LEMBERG  <wl@gnu.org>

	[eqn] Add `delim on'.

	* src/preproc/eqn/lex.cpp (start_delim_saved, end_delim_saved):
	New global variables.
	(do_delim): Handle `delim on' to restore previous start and end
	delimiters.

	* src/preproc/eqn/eqn.man, NEWS: Document it.

2013-01-02  Deri James  <deri@chuzzlewit.myzen.co.uk>

	[gropdf] Various minor fixes.

	* src/devices/gropdf/gropdf (do_x) <'X'> <'pdfpic'>: Using

	\X'pdf: pdfpic'

	with a zero width now works correctly.

	(LoadPDF): Scale width in proportion to given height.

	(do_s): In some circumstances a font size change is emitted before
	current font is established.  Fix handles this situation.

2012-12-30  Werner LEMBERG  <wl@gnu.org>

Version 1.22.1 released
=======================

	Due to CVE-2012-3386, ftp.gnu.org rejected uploading of version
	1.22 -- in other words, 1.22 has never been released.

	* NEWS, REVISION, doc/groff.texinfo, doc/webpage.ms: Updated.

	* Makefile.in (NOMAKEDIRS): Updated.

2012-12-30  Werner LEMBERG  <wl@gnu.org>

	* src/libs/gnulib/*: Update `gnulib' files.

	Because we currently don't support `gnulib-tool' directly but add
	everything to the CVS repository, and many internal details of the
	gnulib setup has changed, it is necessary to do redo the import.

	. Temporarily rename `src/libs/gnulib' to `src/libs/gnulib.old'.

	. Call

	    gnulib-tool --create-testdir \
	                --dir=src/libs/gnulib \
	                wcwidth

	. Manually move directories `src/libs/gnulib/gl{lib,m4}' to
	`src/libs/gnulib/{lib,m4}', and do `s/gllib/lib/' and `s/glm4/m4/'
	in all files to `convert' the gnulib testbed to a standard gnulib
	configuration as maintained by gnulib-tool.  Additionally, remove
	the directory `src/libs/gnulib/gltests' and the references to
	`gltests' in all files.

	(All of this could be done with a script, but I hope that this is
	eventually replaced with migrating groff as a whole to gnulib and
	its setup).

	. Call

	    gnulib-tool --add-import \
	                --dir=src/libs/gnulib \
	                wcwidth

	to update everything.

	. Merge the changed, new, and deleted files into `gnulib.old',
	delete `gnulib', rename `gnulib.old' to `gnulib', then commit.

2012-12-28  Werner LEMBERG  <wl@gnu.org>

	[doc] More documentation generation rules.

	* doc/Makefile.in (.texinfo.txt): New rule.
	(.texinfo.html): Use `LANG='.

	* doc/fixinfo.sh: Make it work with makinfo 4.13 also.

2012-12-28  Werner LEMBERG  <wl@gnu.org>

	Split ChangeLog.

	* ChangeLog: Split off older entries into...
	* ChangeLog.121: this new file.

2012-10-17  Deri James  <deri@chuzzlewit.myzen.co.uk>

	* src/devices/gropdf/gropdf.pl (do_D): The command \D't N' moves
	horizontal position by 'N'.  gropdf now obeys this rule.
	(do_t): Fixed kerning issue where width of non-kerned text could
	be wrongly calculated using previous kern factor.

2012-09-21  Werner LEMBERG  <wl@gnu.org>

	[gropdf] Various minor fixes.

	* font/devpdf/Foundry.in: Add font path to debian `gsfonts'
	package.

	* font/devpdf/util/BuildFoundries.pl: Handle missing fonts in a
	more sane way, do NOT abort the complete make run!

	* src/devices/gropdf/gropdf: Accept papersize names (i.e. A4) as
	either upper or lower case.  The -p (papersize) option should be
	length,width (currently reversed - width,length)

	* src/devices/gropdf/pdfmom.pl: Support use of GROFF_BIN_PATH.

2012-09-11  Ralph Corderoy  <ralph@inputplus.co.uk>
	    Werner LEMBERG <wl@gnu.org>

	* src/preproc/tbl/tbl.man: Better document `d' column specifier.

2012-08-31  Deri James  <deri@chuzzlewit.myzen.co.uk>

	Add `pdfmom' to handle mom documents with gropdf.

	* Makefile.in (OTHERDIRS): Move contrib/mom to be run after
	devices/gropdf.

	* src/devices/gropdf/gropdf.pl: Various fixes:

	. Correct image scaling issue.
	. Handle relative horizontal movement 'h' followed by absolute

	* src/devices/gropdf/pdfmom.pl: New wrapper for mom (pdfmom)
	using gropdf or grops driver.
	* src/devices/gropdf/pdfmom.man: New man page.
	* src/devices/gropdf/Makefile.sub: Updated to handle new files.

	for the full report.

2012-08-08  Eric S. Raymond  <esr@thyrsus.com>

	TBLization, as discussed on the list.  There's a rewrite of
	this file in planning, but this gets the content clean for now.

	* tmac/groff_mdoc.man: In this file.

2012-08-09  Werner LEMBERG  <wl@gnu.org>

	Provide proper Unicode mapping from and to dotless j.

	* src/libs/libgroff/glyphuni.cpp (glyph_to_unicode_list),
	src/libs/libgroff/uniglyph.cpp (unicode_to_glyph_list): Add it.

2012-08-08  Eric S. Raymond  <esr@thyrsus.com>

	Added Unicode code point for dotless j.

	* man/groff_char.man: In this file.

2012-08-08  Werner LEMBERG  <wl@gnu.org>

	* man/groff_char.man: Clean-ups.

2012-08-08  Eric S. Raymond  <esr@thyrsus.com>

	Elimination of nasty presentation-level macro tangles makes
	structural translation to XML possible.

	* man/groff_char.man: Clean up the mess, use real TBL tables.

2012-07-23  Eric S. Raymond  <esr@thyrsus.com>

	More elimination of low-level troff hackery in the documentation
	so it can be lifted to structural markup.

	* tmac/groff_me.man: Use TBL rather than wacky diversions and .ti
	requests.

2012-07-24  Werner LEMBERG  <wl@gnu.org>

	Fix appearance of groff.texinfo's HTML output.

	Cartouches within an `example' environment don't work.

	* doc/groff.texinfo (CartoucheExample, endCartoucheExample): New
	macros.  Use them where appropriate.

2012-07-17  Ingo Schwarze  <schwarze@usta.de>

	[mdoc] Make `Fl' correctly restore fonts.

	* tmac/doc.tmac (doc-flag-recursion): Do it.

2012-07-07  Eric S. Raymond  <esr@thyrsus.com>

	* src/preproc/eqn/eqn.man, src/preproc/grn/grnn.man,
	src/devices/grodvi/grodvi.man, src/devices/grolj4/grolj4.man,
	src/devices/grops/grops.man, src/utils/lkbib/lkbib.man,
	src/utils/indxbib/indxbib.man, src/utils/tfmtodit/tfmtodit.man,
	src/utils/xtotroff/xtotroff.man:
	Remove running text in the synopses of various manual pages,
	as it badly screws up attempts to mechanically parse them.

	* contrib/mom/groff_mom.man: Use .URL rather than .UR/.UE, as this
	is now preferred for manual pages.

2012-07-03  Werner LEMBERG  <wl@gnu.org>

	Fix Unicode mapping of Greek stroked and curly phi.

	Problem reported by Alkis Georgopoulos <alkisg@gmail.com>;
	see

	https://bugs.launchpad.net/ubuntu/+source/groff/+bug/1008115

	* src/libs/libgroff/uniglyph.cpp (unicode_to_glyph_list): Flip
	values of U+03C6 and U+03D5.

2012-06-13  Deri James  <deri@chuzzlewit.demon.co.uk>

	* src/devices/gropdf/gropdf.pl: When using variable page
	sizes (with \X'papersize ...') ensure final page is correct
	size.

2012-05-24  Werner LEMBERG  <wl@gnu.org>

	* src/roff/grog/grog.pl (process): Fix .so handling.

	This does the same as the previous commit.

2012-05-24  Denis M. Wilson  <dmw@oxytropis.plus.com>

	* src/roff/grog/grog.sh: Fix .so handling.

	See

	http://lists.gnu.org/archive/html/bug-groff/2012-05/msg00000.html

	for the report and the bug fix.

2012-05-24  Ivan Shmakov  <oneingray@gmail.com>

	Add some generic fallback characters.

	* tmac/fallbacks.tmac: New file.
	* tmac/troffrc: Include it.
	* tmac/Makefile.sub (NORMALFILES): Include it.

2012-05-20  Deri James  <deri@chuzzlewit.demon.co.uk>

	* doc/groff.texinfo: Add extra info about `.asciify'.
	Document new gropdf options -u and -s.

	* src/devices/gropdf/gropdf.man: Remove references to Type 42
	fonts, they do not work in PDFs.

	Document new option -s which adds `statistics' line to end of PDF
	file showing number of pages in document.  This has always been
	the default behaviour (to add this line), all other software seems
	to ignore it as intended, but `gs' sometimes complains, so the
	default is now to omit the statistics.

	Document new option -u[cmapfilename] to allow a user ToUnicode
	CMap instead of gropdf's default.  If no `cmapfilename' given then
	do not include any ToUnicode CMap.

	* src/devices/gropdf/gropdf.pl <top>: Allow `bundled' flags on
	command line (i.e. -de = -d -e).

	Use $RT_SEP as multi path separator, not hard coded `:'.  Update
	all users.

	New flags -u and -s.  Once a custom papersize has been set as
	\X'papersize x,y' make it sticky so all following pages use custom
	size.  When importing pdf with \X'pdf: pdfpic ...' do not compress
	objects which are already compressed! This caused problems with
	PDFs created with ImageMagick, now fixed.

	(IsText, PutLine, do_t): The troff `u' command can contain a
	kerning adjustment number, this was not being handled, now fixed.

	(do_c): The troff `c' command was not being handled correctly, now
	fixed.
	(FindChar, RemapChr, do_N): Handle fonts with more than 255 glyphs.
	($ucmap): Define CMap ToUnicode to convert ligatures
	(fl,fi,ff,ffl,ffi) back to individual characters, useful for
	cut'n'paste and text searching.
	(LoadFont): Handle it.
	(ToPoints, GetPoints): Handle `z' unit.
	(do_x, FixPDFColour, PutHotSpot): Allow Annotation colour to be
	groff colour, i.e. 0-65535 *3, or #rrggbb, or #rrrrbbbbgggg.
	(do_p):The papersize width/length in switch -p were reversed,
	corrected.

	* src/devices/gropdf/Makefile.sub (gropdf): Use $RT_SEP.
	Use $fontpath rather than $fontdir (this ensures site-font is
	included in searches).

	* tmac/pdf.tmac (PDFBOOKMARK.VIEW, PDFHREF.VIEW, PDFPAGE.Y): Fix
	strings.
	(pdfbookmark): Correct handling of bookmark levels.
	Convert \[em] to hyphen in bookmarks

	Rather use -N than -T for "named" bookmarks (-T already used for
	"tag" in pdfmark.tmac)

	(.pdfclean): New macro which attempts to asciify bookmark text.
	(.pdfpagename): New wrapper macro for \X'pdf: pagename'.
	(.pdfswitchtopage): New wrapper macro for \X'pdf: switchtopage'.

2012-03-10  Werner LEMBERG  <wl@gnu.org>

	Fix compiler warnings.

	* src/preproc/html/pre-html.cpp (alterDeviceTo): Avoid ambiguous
	if-else clause.

	* src/preproc/grn/main.cpp (sccsid): Comment out.

	* src/roff/troff/number.cpp (parse_expr) <case '*'>: Add cast.

	* src/devices/xditview/Makefile.sub (EXTRA_CFLAGS): Add `-Dlint'
	so that unused static ID arrays don't cause a warning.

	(Some) problems reported by Bjarni Ingi Gislason
	<bjarniig@rhi.hi.is>.

2012-03-05  Werner LEMBERG  <wl@gnu.org>

	* tmac/an-ext.tmac (SY): Handle argument with spaces correctly.

	Problem reported by Bjarni Ingi Gislason <bjarniig@rhi.hi.is>.

2012-03-01  Bjarni Ingi Gislason  <bjarniig@rhi.hi.is>

	[an-old] Fix warnings.

	* tmac/an-old.tmac (an-init): Insert missing braces.

2012-02-26  Werner LEMBERG  <wl@gnu.org>

	Update configuration files from `gnulib' and `config' repositories.

	This also fixes a problem with `iconv' on Solaris 10, as reported
	in

	http://lists.gnu.org/archive/html/bug-groff/2012-02/msg00007.html

	* configure.ac: Call `gl_LOCALCHARSET.
	Call `AM_ICONV' as C++.

	* config.guess, config.rpath, config.sub, install-sh, mkinstalldir:
	Updated.

	* m4/codeset.m4, m4/glib21.m4, m4/iconv.m4, m4/lib-ld.m4,
	m4/lib-link.m4, m4/lib-prefix.m4: Updated.
	* m4/fcntl-o.m4, m4/localcharset.m4: New files.

	* Makefile.in: Updated.

	* src/include/localcharset.h, src/libs/libgroff/config.charset,
	src/libs/libgroff/localcharset.c: Updated.

	* aclocal.m4, configure, src/include/config.hin: Regenerated.

2012-02-20  Werner LEMBERG  <wl@gnu.org>

	Update `gnulib' files.

	The invocation was

	gnulib-tool --add-import \
	              --dir=src/libs/gnulib \
	              wcwidth

	Additionally, src/libs/gnulib/configure.ac was adjusted from a
	`test' run as described in the change from 2010-12-13.

	* src/libs/gnulib/*: Updated.

2012-02-15  Deri James  <deri@chuzzlewit.demon.co.uk>

	[gropdf] Fixes and omissions.

	* src/devices/gropdf/gropdf.pl (<top>, do_u): Add facility to
	handle track kerning (.tkf).

	(do_x, do_p, do_t): If pages are reordered using `pagename' and
	`switchtopage' keep track of outline bookmarks.
	(do_x): Handle multiple files on gropdf command line, stitch
	multiple groff_out files together.  In the main read loop any argc
	values not consumed by options are taken as input files and
	processed in order.  What prevented it working properly before is
	the way an `x i' (initialize) record has been handled.  It now
	processes the initialization code only in the first file.

	(PutHotSpot): Allow user to control size of hotspot bounding box
	on clickable links by setting PDFHREF.LEADING

	* tmac/pdf.tmac (PDFHREF.LEADING): Adjust value.
	(pdf*href): Pass value of PDFHREF.LEADING to gropdf.

2012-02-10  Deri James  <deri@chuzzlewit.demon.co.uk>

	[gropdf] Fix compatibility issues with pdfmark.

	* tmac/pdf.tmac (PDFHREF.VIEW.LEADING): Fix value.
	(pdf:href.opt-X): Add check for -X option for .pdfhref.

2012-02-08  Werner LEMBERG  <wl@gnu.org>

	* src/preproc/pic/main.cpp (do_file): Check for invalid characters.

	Problem reported by Doug McIlroy <doug@cs.dartmouth.edu>.

2012-01-25  Ingo Schwarze  <schwarze@usta.de>

	[mdoc] * tmac/doc-syms: Fix meaning of XBD acronym.

2012-01-25  Tadziu Hoffmann  <hoffmann@usm.uni-muenchen.de>

	* tmac/e.tmac (bl): Make it work inside blocks.

	See threads starting with

	http://lists.gnu.org/archive/html/groff/2011-12/msg00055.html
	http://lists.gnu.org/archive/html/groff/2012-01/msg00000.html

2012-01-10  Bruno Haible  <bruno@clisp.org>

	Fix handling of MAKEFLAGS variable.

	* Makefile.in (MAKE_K_FLAGS): Improved definition,
	as explained and discussed in

	http://lists.gnu.org/archive/html/groff/2012-01/msg00039.html

2012-01-03  Ingo Schwarze  <schwarze@usta.de>

	Improve parallel builds.

	Some hdtbl and mom examples want PostScript formatting which
	requires the `DESC' file to be ready; however, the top-level
	`Makefile.in' doesn't currently enforce the proper order of
	building of `font/dev' before `contrib/hdtbl', `contrib/mom', and
	so on.

	Given that `font/dev' and the contrib examples are in different
	child processes of the recursive make system, it doesn't seem
	possible to solve this using clean Makefile dependencies.  We now
	enforce the order by splitting the shell command invoking
	recursive make in the top level `Makefile.in'.

	* Makefile.in (ALLDIRS): Remove `OTHERDIRS'.
	(dodirs): Updated.
	(`$(TARGETS)'): Handle `OTHERDIRS' separately.

2012-01-03  Kristaps Dzonsons  <kristaps@bsd.lv>

	[mdoc] Add `-isoC-2011'.

	* tmac/doc-syms (doc-str-St--isoC-2011): Add it.
	* tmac/groff_mdoc.man: Document it.

2011-12-26  Deri James  <deri@chuzzlewit.demon.co.uk>

	* font/devpdf/Makefile.sub: Only build fonts on first `make'.

2011-12-08  Werner LEMBERG  <wl@gnu.org>

	* doc/groff.texinfo (.tl): Improve documentation.
	Wording suggested by Keith Marshall
	<keithmarshall@users.sourceforge.net>.

2011-12-01  Werner LEMBERG  <wl@gnu.org>

	[me] Fix behaviour of centered block.

2011-03-29  Christian Weisgerber  <naddy@mips.inka.de>

	Fix build with non-GNU make.

	* Makefile.in ($TARGETS): We must not pass `$MDEFINES' recursively
	down to the sub-makes started in src/libs/gnulib, because that
	directory has its own values for `$top_srcdir' etc., and
	overriding those from the command line will cause the build to
	fail.  Currently, `$MAKEOVERRIDES' will prevent the recursive
	passing of those overrides with GNU make, but not with other
	make(1) implementations.  It looks like all targets that require
	`$MDEFINES' set them explicitly anyway, so we shouldn't need to
	set `$MDEFINES' on the top level.
