	of nested comments by checking that the comment-starter we found
	does indeed match the comment-ender.

	* w32menu.c (w32_menu_display_help): Call show_help_echo with
	non-zero ok_to_overwrite_keystroke_echo argument.

2000-07-10  Gerd Moellmann  <gerd@gnu.org>

	* xdisp.c (try_window_id): If changes are all below what is

2000-07-05  Andrew Innes  <andrewi@gnu.org>

	* vm-limit.c (check_memory_limits) [REL_ALLOC]: Use real_morecore
	when non-NULL instead of __morecore, to take account of buffer
	memory.  This also solves a problem with spurious memory warnings
	on Windows.

	* ralloc.c: Make real_morecore non-static.

	* eval.c (internal_condition_case): Comment out abort if
	interrupt_input_blocked is not zero.

2000-07-05  Stefan Monnier  <monnier@cs.yale.edu>

	* w32menu.c (w32_menu_display_help):
	* xmenu.c (menu_help_callback): Use show_help_echo.

	(x_produce_image_glyph, x_append_stretch_glyph): Accomodate to
	changes in struct glyph starting 1999-12-27.  Some bit-fields of
	struct glyph were not set, which made glyphs unequal when compared
	with GLYPH_EQUAL_P.  Redisplay outputs such glyphs, and flickering
	effects were the result.  This also depended on the contents of
	memory returned by xmalloc.  If flickering happens again, activate
	the code in clear_glyph_row that's in #if 0.  If the flickering is
	gone with that, chances are that it is caused by something
	similar.

	* dispnew.c (clear_glyph_row): Add debug code in #if 0.

	* dispextern.h: Add some comments.

	* window.c (add_window_to_list): Add parameter LIST.
	(window_list): Order list so that, for each frame, windows are
	in canonical order, and so that frames appear in the list in
	the order given by Vframe_list.

	next_window.
	(Fwindow_list): New function.
	(Fother_window): Cleaned up.

	(freeze_window_start): Return int.
	(init_window): New function.
	(syms_of_window): Staticpro Vwindow_list and defsubr Swindow_list.

	redirected to the minibuffer frame.

2000-07-03  Stefan Monnier  <monnier@cs.yale.edu>

	* fns.c (Fputhash): Return `value' rather than nil.

2000-06-30  Gerd Moellmann  <gerd@gnu.org>

	* frame.c (next_frame): Don't check focus redirection in case
	MINIBUF is a window.  Doing so excludes frames using MINIBUF
	unless their focus is redirected, which contradicts the
	specification of next-frame, and leads to infinite loops in
	certain situations when cycling through windows with next-window.

2000-06-30  Kenichi Handa  <handa@etl.go.jp>

	* coding.c (code_convert_region): Even if the length of text is

	(new_lines_size, run_pool, runs_size, runs): New variables.
	(add_row_entry): New function.
	(scrolling_window): Use data structures allocated with xmalloc and
	held in global variables, instead of allocating them with alloca and
	holding them in local variables.  Use a larger hash table whose
	size depends on glyph matrix sizes.  Don't use bzero to clear the
	hash table; instead, clear used slots only.

	* fns.c (next_almost_prime): Make it externally visible.

	* lisp.h (next_almost_prime): Add prototype.

	* s/isc4-0.h (sigunblock): Define.

	* s/sco5.h (sigunblock): Define.

	* config.in (USE_XIM): New define.

	* keymap.c (get_keyelt): For menu-items containing a `:filter
	FILTER', apply FILTER to the menu-item's definition to get the
	real definition to use.

	* lisp.h (QCfilter): External declaration.

	* xfns.c (Fimage_size): New function.
	(syms_of_xfns): Defsubr it.

	and inconsistent EOL types.

2000-06-22  Gerd Moellmann  <gerd@gnu.org>

	* xrdb.c (x_load_resources): Add default resource for scroll bar's

	effects, one visible being that the cursor of a frame created with

	(redisplay_window) <cursor movement in unchanged window>: When
	point has been moved forward, and PT is at the end of the cursor
	row, don't place the cursor in the next row if the cursor row ends
	in the middle of a character or at ZV.

	* dispextern.h (struct it): Add starts_in_middle_of_char_p.

	padding glyph not fitting on line as whole character not
	fitting on line.

	* xterm.c (x_produce_glyphs): Don't xassert `it->descent > 0';
	this isn't true for images with `:ascent 100'.

2000-06-06  Kenichi Handa  <handa@etl.go.jp>

	* buffer.c (Fset_buffer_multibyte): Don't make the current buffer
	as modified if it is originally unmodified.

	* term.c (encode_terminal_code): Change the way to check if
	terminal coding does any conversion.
	(append_glyph): Set glyph->pixel_width correctly.

	* fns.c (Fy_or_n_p): Cancel busy-cursor.

2000-03-08  Stefan Monnier  <monnier@cs.yale.edu>

	This is a big redesign of failure-stack and register handling, prompted
	by bugs revealed when trying to add shy-groups.  Overall, what happened
	is that loops are now structured a little differently, groups can be
	shy and the code is a little simpler.

	* regex.h: Update the copyright.
	(RE_SHY_GROUPS): New value.
	(RE_UNMATCHED_RIGHT_PAREN_ORD): Renumber.
	(RE_SYNTAX_EMACS): Add RE_SHY_GROUPS.

	* regex.c (enum re_opcode_t): Remove jump_past_alt,
	maybe_pop_jump, push_dummy_failure and dumy_failure_jump.  Add
	on_failure_jump_(exclusive, loop and smart).  Also fix the comment
	for (start|stop)_memory since they now only take one argument (the
	second has becomes unnecessary).
	(print_partial_compiled_pattern): Adjust for changes in
	re_opcode_t.
	(print_compiled_pattern): Use %ld to printf long ints and flush to
	make debugging a little easier.

	(ENSURE_FAIL_STACK): New macro for PUSH_FAILURE_(REG|POINT).
	(PUSH_FAILURE_REG, POP_FAILURE_REG, CHECK_INFINITE_LOOP): New
	macros.
	(PUSH_FAILURE_POINT): Don't push registers any more.  The pattern
	address pushed is not the destination of the jump but the source
	of it instead.
	(NUM_FAILURE_ITEMS): Remove.
	(POP_FAILURE_POINT): Adapt to the new stack structure (i.e. pop
	registers before the actual failure point).  Don't hardcode any
	meaning for str==NULL anymore.
	(union register_info_type, REG_MATCH_NULL_STRING_P, IS_ACTIVE)
	(MATCHED_SOMETHING, EVER_MATCHED_SOMETHING, SET_REGS_MATCHED):

	(FIXUP_ALT_JUMP): New macro.
	(regex_compile): Add shy-groups Change loops to use
	on_failure_jump_smart&jump instead of
	on_failure_jump&maybe_pop_jump.  Change + loops to eliminate the
	initial (dummy_failure_)jump.  Remove c1_base (looks like unused
	variable to me).  Use `jump' instead of `jump_past_alt' and don't
	bother with push_dummy_failure in alternatives since it is now
	unnecessary.  Use FIXUP_ALT_JUMP.  Eliminate a useless `#ifdef
	emacs' for (re)allocating the stack.
	(re_compile_fastmap): Remove dead variables i and num_regs.  Exit
	from loop when bufp->can_be_null rather than jumping to `done'.
	Avoid jumping backwards so as to ensure termination.  Use
	PATTERN_STACK_EMPTY and POP_PATTERN_OP.  Improved handling of
	backreferences.  Remove dead code in handling of `anychar'.
	(skip_noops, mutually_exclusive_p): New functions taken from the
	handling of `maybe_pop_jump' in re_match_2_internal.  Slightly
	improve mutually_exclusive_p to handle ".+\n".
	(lowest_active_reg, highest_active_reg,
	NO_(LOWEST|HIGHEST)_ACTIVE_REG) Remove.
	(re_match_2_internal): Use %p instead of 0x%x when printf'ing
	ptrs.  Don't SET_REGS_MATCHED anymore.  Remove many dead
	variables.  Push register (in `start_memory') on the stack rather
	than storing it in old_reg(start|end).  Remove the cycle detection
	from `stop_memory', replaced by the use of on_failure_jump_loop
	for greedy loops.  Add code for the new on_failure_jump_<foo>.
	Remove ad-hoc code in `on_failure_jump' to push more registers in
	the case of a loop.  Take out code from `maybe_pop_jump' into
	separate functions and adapt it to the semantics of
	`on_failure_jump_smart'.  Remove jump_past_alt, dummy_failure_jump
	and push_dummy_failure.  Remove dummy_failure handling and
	handling of `failures to jump to on_failure_jump' (this last one
	was already dead code, it seems).
	(group_match_null_string_p, alt_match_null_string_p)
	(common_op_match_null_string_p): Remove.

2000-03-08  Dave Love  <fx@gnu.org>
