	* syntax.c (back_comment): Use one switch rather than a few `if's.
	Obey open_paren_in_column_0_is_defun_start.

	of nested comments by checking that the comment-starter we found
	does indeed match the comment-ender.
	(scan_sexps_forward, scan_sexps_forward):

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

	* xdisp.c (try_window_id): If changes are all below what is
	displayed in the window, and point is in the window, we still

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.

	(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.

	next_window.
	(Fwindow_list): New function.

	(syms_of_window): Staticpro Vwindow_list and defsubr Swindow_list.

	* 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.

	* 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.

	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

2000-03-19  Gerd Moellmann  <gerd@gnu.org>

	* xfns.c (select_visual): Don't set dpyinfo->n_planes to the

2000-03-13  Stefan Monnier  <monnier@cs.yale.edu>

	* regex.c: Declare a new type `re_char' used throughout the code
	for the string char type.  It's `const unsigned char' to match the
	rest of Emacs.  Consistently make sure all pointers to strings use
	it and make sure all pointers into the pattern use `unsigned
	char'.
	(re_match_2_internal): Use `PREFETCH+STRING_CHAR' instead of

	* 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.
	(union fail_stack_elt): Make the integer unsigned.
	(struct fail_stack_type): Add a `frame' element.
	(INIT_FAIL_STACK): Init `frame' as well.

	(NUM_REG_ITEMS): Remove.
	(NUM_NONREG_ITEMS): Adjust.
	(FAILURE_PAT, FAILURE_STR, NEXT_FAILURE_HANDLE)
	(TOP_FAILURE_HANDLE): New macros for the cycle detection.
	(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):
	Remove.
	(REG_UNSET_VALUE): Use NULL (why not?).
	(compile_range): Remove declaration since it doesn't exist.
	(struct compile_stack_elt_t): Remove inner_group_offset.
	(old_reg(start|end), reg_info, reg_dummy, reg_info_dummy): Remove.
	(regex_grow_registers): Remove dead code.
	(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>

	(detect_eol): selects detect_eol_type_XXX to call according to
	cooding->category_idx.
