 src/insdel.c (invalidate_buffer_caches): New function, consolidated
 from part of prepare_to_modify_buffer.
 (insert_from_gap, prepare_to_modify_buffer):
 src/coding.c (code_convert_region, code_convert_string): Call
 invalidate_buffer_caches.
 src/lisp.h (invalidate_buffer_caches): Add prototype.

 src/w32term.c (x_update_window_end): Don't invalidate the entire
 mouse-highlight info, just signal frame_up_to_date_hook that mouse
 highlight needs to be redisplayed.

* lisp/org/ob-python.el (org-babel-python-with-earmuffs):
Rename from org-babel-python-with-earmufs.  All uses changed.
(org-babel-python-without-earmuffs):
Rename from org-babel-python-without-earmufs.  All uses changed.

* src/lisp.h (DEBUGGER_SEES_C_MACROS): Likewise.
It apparently doesn't work for GCC 3, and I suppose it's more
trouble than it's worth to worry about this.

 src/doc.c (Fsubstitute_command_keys): Inhibit modification hooks
 while we are using Vprin1_to_string_buffer.

Fixes: debbugs:15907

 src/keymap.c (describe_map): Don't crash if PT is 1 both before and
 after inserting the description string.

Reported by Eli Zaretskii in
<http://lists.gnu.org/archive/html/emacs-devel/2013-11/msg00489.html>.
(pre_value): New function.
(count_trailing_zero_bits): Use it.

 src/lisp.h (DEBUGGER_SEES_C_MACROS) [GCC < v3.5]: Pessimistically
 assume C macros are not supported even under -g3 in these old GCC
 versions.

* src/minibuf.c (Ftry_completion, Fall_completions)
(Ftest_completion): Use FUNCTIONP.  (Bug#15889)

* src/lisp.h (DEFINE_GDB_SYMBOL_BEGIN, DEFINE_GDB_SYMBOL_END):
Define to empty if DEBUGGER_SEES_C_MACROS is defined.
This avoids placing unnecessary constants into the Emacs code.

 src/keyboard.c (make_ctrl_char) [HAVE_NTGUI]: Now externally visible
 for Cygwin w32 build.
 src/xdisp.c (erase_phys_cursor) [HAVE_NTGUI]: Now externally visible
 for Cygwin w32 build.

* configure.ac (BITSIZEOF_SIZE_T, SIZEOF_SIZE_T): Remove.
* src/alloc.c (bool_vector_exact_payload_bytes)
(bool_vector_payload_bytes): Remove.
(bool_vector_fill): Return its argument.
* src/alloc.c (bool_vector_fill):
* src/lread.c (read1):
* src/print.c (print_object):
Simplify by using bool_vector_bytes.
* src/alloc.c (make_uninit_bool_vector):
New function, broken out from Fmake_bool_vector.
(Fmake_bool_vector): Use it.  Use tail call.
(make_uninit_bool_vector, vector_nbytes): Simplify size calculations.
* src/data.c (BITS_PER_ULL): New constant.
(ULLONG_MAX, count_one_bits_ll): Fall back on long counterparts
if long long versions don't exist.
(shift_right_ull): New function.
(count_one_bits_word): New function, replacing popcount_bits_word
macro.  Don't assume that bits_word is no wider than long long.
(count_one_bits_word, count_trailing_zero_bits):
Don't assume that bits_word is no wider than long long.
* src/data.c (bool_vector_binop_driver, bool_vector_not):
* src/fns.c (Fcopy_sequence):
* src/lread.c (read1):
Create an uninitialized destination, to avoid needless work.
(internal_equal): Simplify.
(Ffillarray): Prefer tail call.
* src/data.c (bool_vector_binop_driver): Don't assume bit vectors always
contain at least one word.
(bits_word_to_host_endian): Prefer if to #if.  Don't assume
chars are narrower than ints.
* src/data.c (Fbool_vector_count_matches, Fbool_vector_count_matches_at):
* src/fns.c (Fcopy_sequence):
Simplify and tune.
* src/lisp.h (bits_word, BITS_WORD_MAX, BITS_PER_BITS_WORD):
Don't try to port to hosts where bits_word values have holes; the
code wouldn't work there anyway.  Verify this assumption, though.
(bool_vector_bytes): New function.
(make_uninit_bool_vector): New decl.
(bool_vector_fill): Now returns Lisp_Object.

* lib-src/ebrowse.c (xstrdup):
* lib-src/etags.c (savenstr):
* lwlib/lwlib.c (safe_strdup):
* src/xfns.c (xic_create_fontsetname):
* src/xrdb.c (gethomedir): Prefer tail calls.
* lib-src/etags.c (concat): Omit unnecessary assignment.

This is safer, and it's what w32fns.c does.

that requires a return value.
(Fset_buffer_modified_p): Take advantage of this change to do
a tail call.

* src/buffer.c (Frestore_buffer_modified_p): Sync it with
Fset_buffer_modified_p.
(Fforce_mode_line_update): New function, moved from subr.el.
(Fset_buffer_modified_p): Use them.
(syms_of_buffer): Defsubr Fforce_mode_line_update.

This avoids undefined behavior when subtracting pointers into
different aways.  On my platform it also makes the code a tad
smaller and presumably faster.

* src/keyboard.c (command_loop_1): Use region-extract-function.
* src/insdel.c (Qregion_extract_function): Not static any more (can we
stop pretending that these vars can benefit from being marked static?).

 src/search.c (find_newline): If buffer text is relocated during the
 "dumb loop", adjust C pointers into buffer text to follow suit.

for conversion.

Fixes: debbugs:15837

 src/fileio.c (Finsert_file_contents): Invalidate the newline cache
 for the entire range of inserted characters.

* src/xfaces.c (lface_fully_specified_p): Let distant-foreground be
unspecified.
(realize_default_face): Remove assignment to distant-foreground if
unspecified.

Fixes: debbugs:15815
