-
-	Speed up troff.
-
-	* src/include/ptable.h (PTABLE): Make hash tables much more sparse
-	by changing the ratio `FULL_NUM/FULL_DEN' from 2/3 to 1/4.  This
-	increases the allocated memory by about 200kByte (which is nothing
-	today) but assures that there aren't extremely long searches for a
-	free hash slot in case that the hash function doesn't return a free
-	one.  Due to the nature of the entries in uniuni.cpp, the used hash
-	function in ptable.cpp is not optimal, but using a sparse array
-	compensates this.
-
-2010-12-20  Werner LEMBERG  <wl@gnu.org>

-2010-12-20  Werner LEMBERG  <wl@gnu.org>
-
-	Speed up access to cflags values.
-
-	We now recompute the cflags values for all charinfo objects if
-	`.class' has been called.
-
-	* src/roff/troff/charinfo.h: Add external references to `class_flag'
-	and `get_flags'.
-	(charinfo): `get_flags' no longer has a return value.
-	(charinfo::overlaps_horizontally, charinfo::overlaps_vertically,

-	(charinfo::charinfo): Call `get_flags' member function.
-	(get_flags): New global function which iterates over all entries in
-	the charinfo dictionary.
-	(charinfo::get_flags): Set `flags' directly.
-
-2010-12-19  Werner LEMBERG  <wl@gnu.org>
-

-
-	* src/roff/troff/charinfo.h (charinfo::contains): Add optional
-	boolean argument.
-	* src/roff/troff/input.cpp (define_class, charinfo::contains): Check
-	for cyclic nesting.
-
-2010-12-18  Werner LEMBERG  <wl@gnu.org>
-
-	Improve CJK support with new values for `.cflags'.
-
-	This patch introduces three new values to `.cflags':
-
-	  don't break before character: 128
-	  don't break after character:  256
-	  allow inter-character break:  512
-
-	They are handled differently if compared to other cflags values:
-
-	  (1) hcode values are completely ignored
-	  (2) similar to kern values, and contrary to the other cflags
-	      values, troff looks at pairs of characters to decide whether a
-	      break gets inserted
-
-	A yet-to-be-written patch should add inter-character spacing if
-	those flags are active; currently, only zero-width breakpoints are
-	inserted.
-
-	* src/roff/troff/charinfo.h (charinfo): Change type of `flags' to
-	`int'.  Update callers accordingly.
-	New enum values `DONT_BREAK_BEFORE', `DONT_BREAK_AFTER', and
-	`INTER_CHAR_SPACE'.
-	New member functions `prohibit_break_before',
-	`prohibit_break_after', and `inter_char_space'.
-	* src/roff/troff/input.cpp: Updated.
-
-	* src/roff/troff/node.cpp (inter_char_space_node): New class similar
-	to kern_pair_node, collecting charinfo entities with the
-	abovementioned cflags values.
-	(break_char_type): Add new enum values.
-	(glyph_node::merge_glyph_node): Handle abovementioned cflags values
-	and emit an `inter_char_space_node' if necessary.
-
-	* tmac/ja.tmac: Use new cflags values.
-
-	* doc/groff.texinfo, NEWS, man/groff_diff.man: Document new values.
-
-2010-12-18  Werner LEMBERG  <wl@gnu.org>

-	Remove compiler warning.

-	* src/libs/libgroff/relocate.cpp (msw2posixpath): Remove redundant

-	(break_char_node::add_self, node::add_char): Use it.
-
-2010-12-13  Daiki Ueno  <ueno@unixuser.org>
-	    Werner LEMBERG  <wl@gnu.org>
-
-	Add wide character support to grotty.
-
-	This is a huge patch, mainly by adding the gnulib infrastructure in
-	a separate directory tree (in `src/libs/gnulib/lib') for its
-	`wcwidth' module.  However, the actual changes to native groff
-	source files are just a few lines.
-

-
-	* Makefile.in (NOMAKEDIRS): Updated.
-	(GNULLIBDIRS): Define.

-
-	* src/libs/gnulib/*: New files.  The import was done as follows:
-
-	  . Call
-
-	      gnulib-tool --create-testdir \
-	                  --dir=src/libs/gnulib \
-	                  wcwidth
-
-	    to get a testbed.
-
-	  . Manually move directories src/libs/gl{lib,m4} to
-	    src/libs/{lib,m4}, and do s/gllib/lib/ and s/glm4/m4/ everywhere
-	    to `convert' the gnulib testbed to a standard gnulib
-	    configuration as maintained by gnulib-tool.
-
-	  . Call
-
-	      gnulib-tool --add-import \
-	                  --dir=src/libs/gnulib \
-	                  wcwidth
-
-	    to update everything.
-

-
-	Implement support for character classes.
-
-	This patch uses standard C++ headers, contrary to the rest of groff.

-	[troff]: Fix hyphenation problem with kerned letters.
-	Problem reported by Steve Izma <sizma@golden.net>.
-
-	* src/roff/troff/node.cpp
-	(kern_pair_node::add_discretionary_hyphen): Compute `tf' using the
-	first node, `n1'.  `n2' might be another kerning node, and the
-	`get_tfont' member function isn't defined then.

-2009-09-01  Michael Cain  <mcain6925@comcast.net>
-
-	[pic] Fix a border case for arc computation.
-
-	* src/preproc/pic/object.cpp (object_spec::make_arc): It can happen
-	that test `radius < d' in the loop is satisfied, but the difference
-	in the two values is on the order of 1e-10.  If `radius' is small,
-	doubling the value can lead to a fairly gross error.
-
-	The original code appears to have been intended to deal with the
-	situation when radius is orders of magnitude less than `d'.  The
-	replacement code simply assigns `radius' the smallest value that
-	avoids problems with the floating point code further on in the
-	routine.

-	Reported by Doug McIlroy <doug@cs.dartmouth.edu>.
-
-	* src/preproc/pic/pic.y: Split `expr' into `expr_lower_than' and
-	`expr_not_lower_than' so that we can handle
-
-	  (1/3)<(1/2)<foo,bar>,baz>
-
-	correctly.  Without the patch, `(1/3)<(1/2)' is handled prematurely
-	as a comparison.
