89 90
	* xterm.c (syms_of_xterm): staticpro Qmodifier_value, Qalt, Qhyper,

	* search.c (find_newline): Rewrite to prefer offsets to pointers.
	This avoids undefined behavior when subtracting pointers into
	different aways.  On my platform it also makes the code a tad
	smaller and presumably faster.

2013-11-11  Stefan Monnier  <monnier@iro.umontreal.ca>

	* keyboard.c (command_loop_1): Use region-extract-function.

2013-11-08  Eli Zaretskii  <eliz@gnu.org>

	* xdisp.c (message_dolog): Make sure the *Messages* buffer has its
	cache-long-scans disabled, since we don't want to call
	prepare_to_modify_buffer (in insert_1_both) for each message we
	display.

	* buffer.h (bset_cache_long_scans): New INLINE function, moved
	from buffer.c.  Improve commentary to the buffer field setter
	functions.

	* buffer.c (bset_cache_long_scans): Static function deleted.
	Improve commentary to the buffer field setter functions.
	(init_buffer_once): Default for cache-long-scans changed to t.

161 162 163 164 165
	* chartab.c (make_sub_char_table): Fix size typo (Bug#15825).
	This bug was introduced in my 2013-06-21 change, and caused
	struct Lisp_Sub_Char_Table objects to be given too many slots,
	which broke 'make -C admin/unidata'.

	Simplify and port recent bool vector changes.
