2005-06-22  Werner LEMBERG  <wl@gnu.org>

	Another round in fixing getopt problems.  Hopefully the last one!
	This time we use the getopt stuff from gnulib and define a prefix
	unconditionally so that there are no collisions with any other
	getopt implementations.  This is a slight waste of space in case
	we already use a GNU getopt implementation, but on
	the other hand it really simplifies life.

	* src/include/getopt.h: Use gnulib version.

	* src/include/getopt_int.h: Use gnulib version.

	* src/include/groff-getopt.h: Removed.  Obsolete now.

	* src/include/lib.h: Regarding getopt, don't handle any platform
	specially; just include getopt.h.
	(__GETOPT_PREFIX): Define (before getopt.h).

	* src/include/Makefile.sub (HDRS): Updated.

	* src/libs/libgroff/getopt1.c, src/libs/libgroff/getopt.c: Use
	gnulib version.

	* src/libs/libgroff/Makefile.sub (EXTRA_CFLAGS): Set
	__GETOPT_PREFIX.

	* src/utils/pfbtops/pfbtops.c, src/utils/xtotroff/xtotroff.c
	(__GETOPT_PREFIX): Define (before getopt.h).

2005-06-21  Werner LEMBERG  <wl@gnu.org>

	* src/include/lib.h: Provide a fix for Mac OS X to not include
	groff-getopt.h.

2005-06-20  Denis M. Wilson  <dmw@oxytropis.plus.com>

	* font/devps/prologue.ps (EP): Dont' use `bind'.  Reason: Using
	`bind' to define a procedure which contains `showpage' means that an
	invocation of `showpage' may execute wrongly (the exact effect
	depending on the interpreter).  Not usually a problem except under
	transformations, such as combining pages.
	(PEND): Don't call `clear'.  Reason: Using `clear' in the definition
	of /PEND means that stack underflow will occur if the stack is
	deliberately non-empty before document inclusion.  If included
	files are found to be generally badly behaved, we could replace the
	`clear' with `mark' in /PBEGIN and `cleartomark' in /PEND (I've
	never found this necessary).

2005-06-20  Jörgen Grahn  <jgrahn@algonet.se>

	* src/preproc/soelim/soelim.cpp (do_file): Append trailing zero
	earlier to get correct error message.

2005-06-15  Werner LEMBERG  <wl@gnu.org>

	Another try to update getopt files.  This time we add a dummy
	gettext.h file to satisfy the dependency.

	* src/include/getopt.h, src/libs/libgroff/getopt.c,
	src/libs/libgroff/getopt1.c: Updated from GNU libc CVS.

	* src/include/getopt_int.h: New file (from GNU libc CVS).

	* src/include/gettext.h: Dummy file which just defines a gettext()
	macro.

	* src/include/groff-getopt.h: Updated.

	* src/include/Makefile.sub (HDRS): Add getopt_int.h and gettext.h.


	* src/libs/libdriver/input.cpp (IntArray): Remove superfluous
	`const' keywords in return value.

	* src/preproc/html/pushback.cpp (pushBackBuffer::~pushBackBuffer):
	Remove redundant variable `old'.
	(pushBackBuffer::skipToNewline): Remove redundant variable `ch'.

	* src/preproc/tbl/main.cpp (process_table): Remove redundant
	variable `c'.


	Fix more friend name injection problems since modern C++ compilers
	fail otherwise.  We simply provide (global) declarations for all
	functions declared as friends.  This is not really necessary but
	doesn't harm.

	* src/preproc/eqn/lex.cpp: Provide declarations for get_char,
	peek_char, and get_location.

	* src/preproc/refer/ref.h: Provide declarations for
	compare_reference, same_reference, same_year, same_date,
	same_author_last_name, and same_author_name.

	page_offset.

	vertical_spacing, post_vertical_spacing, line_spacing, line_length,
	indent, temporary_indent, do_underline, do_input_trap, set_tabs,
	margin_character, no_number, number_lines, leader_character,
	tab_character, hyphenate_request, no_hyphenate,
	hyphen_line_max_request, hyphenation_space_request,
	hyphenation_margin_request, line_width, tabs_save, tabs_restore,
	line_tabs_request, widow_control_request, and do_divert.

	* src/roff/troff/input.cpp: Provide declaration for chop_macro.

	* src/roff/troff/node.cpp: Provide declarations for class
	tfont_spec.
	Provide declaration for make_tfont.

2005-02-15  Gaius Mulley  <gaius@glam.ac.uk>

	These patches modify the indentation implementation to use `<p
	style=margin-left: n%>'.  Many thanks to Peter and Larry for
	suggesting this solution.  Grohtml only uses tables for `.IP' and
	related tags when the first operand has a short width.

	Similarly, they modify all vertical space code.  By default, grohtml
	sets up a style sheet which uses no vertical space between `table',
	`pre', and `p' tags.  It forces spaces when it needs them using
	`style="margin-top: 1em"'.

2004-09-19  Keith Marshall  <keith.d.marshall@ntlworld.com>

	This change implements the following features:

	PORPHANS
	  New numeric register: Defines number of lines following LP, PP,
	  QP, IP or XP, which must be kept together, before any automatic
	  page break.  If insufficient space remains on the current page, a
	  page break is forced before the new paragraph begins.

	HORPHANS
	  New numeric register: Sets number of lines of following paragraph
	  which must be kept with a heading, defined by NH or SH, before any
	  automatic page break.  If insufficient space remains on the
	  current page, a page break is forced before the heading.

	GROWPS
	  (Thanks to Joerg van den Hoff, for this idea).

	  New numeric register: Sets the first level of heading (set with
	  NH), which will keep the same point size as body text; e.g. if
	  GROWPS is set to 3, .NH 3, .NH 4, ... will produce headings at the
	  point size specified by \n[PS], but .NH 2 and .NH 1 will have
	  progressively larger point sizes, determined by \n[PSINCR] (see
	  below).

	PSINCR
	  New numeric register: Sets the point size increment for each level
	  of heading, (set with NH), below the threshold level set by
	  GROWPS; e.g. if \n[PS] = 10, \n[GROWPS] = 3 and \n[PSINCR] = 2.0p,
	  then .NH 1 will produce 14pt headings, .NH 2 will produce 12pt,
	  and all other levels will remain at 10pt, (because \n[PS] = 10).

	SH
	  Existing macro now accepts a numeric argument, to make heading
	  size match that of NH with same argument value, when the
	  GROWPS/PSINCR feature is enabled.

	SN-DOT
	  New string, set by NH macro, replaces the existing (undocumented)
	  use of SN, to represent the assigned section number.

	SN-NO-DOT
	  New string, set by NH macro, represents the assigned section
	  number, but omits the terminal period (periods at intermediate
	  levels are retained).

	SN
	  String set by NH macro, originally undocumented, now implemented
	  as an alias for SN-DOT (which reproduces original behaviour).

	* tmac/s.tmac (PORPHANS): New register.
	(par*start): Use it.
	(HORPHANS, GROWPS, PSINCR): New register…
