performance.  Instead of recalculating indentation fully for each
line, sum up indentation depth based only on visited lines.
(ruby-parse-partial): Increase the depth after "do" even when END
is right after it.
(ruby-parse-partial): When END is in the middle of a percent
literal, increase the depth if the delimiter chars belong to the
paren syntax class.

* test/automated/ruby-mode-tests.el
(ruby-move-to-block-skips-percent-literal): New test.

* lisp/play/fortune.el (fortune-compile):
Also make the compiled file if it does not exist at all, not just if it is old.

and break long line.
* font.h (font_range): Adjust prototype.
* composite.c (autocmp_chars): Pass byte position to font_range.
Break long line.  Remove useless prototype and format comment.

Fixes: debbugs:13625

* callproc.c (Fcall_process_region) [!DOS_NT]:
Avoid unnecessary duplicate call to getenv.
* callproc.c (init_callproc):
* dispnew.c (init_display):
* sysdep.c (sys_subshell):
Omit unnecessary cast of getenv or egetenv.

(GC_MARK_STACK): Remove.

(HAVE_DIRENT_H, HAVE_FDOPENDIR, HAVE_FSTATAT, HAVE_MEMRCHR)
(HAVE_WORKING_FSTATAT_ZERO_FLAG, _NETBSD_SOURCE): New macros.

Fix TMPDIR documentation to match the code's behavior.

With this, it should be as good as it was in 23.3, though it's
still pretty bad: the dumped emacs does not run.  See Mark Fleishman in
http://lists.gnu.org/archive/html/help-gnu-emacs/2011-04/msg00287.html
* unexaix.c (start_of_text): Remove.
(_data, _text): Declare as char[], not int, as AIX manual suggests.
(bias, lnnoptr, text_scnptr, data_scnptr, load_scnptr)
(orig_load_scnptr, orig_data_scnptr):
Now off_t, not long, since they are file offsets.
(make_hdr): Use _data, not start_of_data ().
This is the key part of the fix.
(make_hdr, unrelocate_symbols): Use off_t for file offsets.
(unrelocate_symbols): Cast pointers to intptr_t, not to ulong.

This ports to compilers that optimize the external declaration
'int x = 0;' as if it were 'int x;' to shrink the executable.

 src/xdisp.c (try_scrolling): Scroll text up more if point is too close
 to ZV and inside the scroll margin.  This makes sure point is moved
 outside the scroll margin in these cases.

 src/xdisp.c (redisplay_internal): Don't set w->region_showing to the
 marker's position.
 (display_line): Set w->region_showing to the value of
 it->region_beg_charpos, not to -1.  This fixes redisplay
 optimization when cursor is moved up after M->.
 src/window.h (struct window): region_showing can no longer be negative.

* net/tramp-compat.el (top): Declare `remote-file-name-inhibit-cache'
only if it doesn't exist.

* net/tramp-sh.el (tramp-sh-handle-start-file-process): Set
process marker.

 lib/makefile.w32-in (GNULIBOBJS): Add $(BLD)/memrchr.$(O).
 ($(BLD)/memrchr.$(O)): New dependency.

 nt/inc/ms-w32.h: Add prototype for memrchr.

* doc/lispref/keymaps.texi (Scanning Keymaps):
Remove obsolete sentence about meta characters; this changed in 22.1.

* .bzrignore: Add string.h.
* admin/merge-gnulib (GNULIB_MODULES): Add memrchr.
* lib/gnulib.mk, m4/gnulib-comp.m4: Regenerate.

Omit first arg TARGET, as it's always '\n'.  All callers changed.

Fixes: debbugs:13689

* lisp/erc/erc-match.el (erc-match-message): Don't truncate action messages.

This doesn't fix the bug, but it makes progress: Emacs builds now.
* unexaix.c: Include inttypes.h, stdarg.h.
(report_error, report_error_1): Mark as _Noreturn.
(report_error): Don't report the wrong errno.
(report_error_1): Now varargs.  All callers changed.
(make_hdr): Use uintptr_t, not unsigned, when converting pointers
to unsigned.  Don't use ADDR_CORRECT, as it no longer exists.
(write_ptr): Use %p to print address rather than %lx and a cast
to unsigned long.  Grow buffer a bit, to be safer.

Fixes: debbugs:13679

* src/keyboard.c (read_char, read_char_x_menu_prompt)
(read_char_minibuf_menu_prompt):
Replace nmaps+maps with a single `map' arg.
(follow_key): Operate on a single map.
(active_maps): New function.
(test_undefined): Also return true for nil bindings.
(read_key_sequence): Use active_maps to replace the arrays of keymaps with
a single (composed) keymap.  Remember `first_event' to choose the right
set of active keymaps.  Recompute the set of keymaps after receiving
the first event.  Remove GOBBLE_FIRST_EVENT.
(syms_of_keyboard): Remove inhibit_local_menu_bar_menus.
* src/keyboard.h (read_char): Update declaration.
* src/lread.c (read_filtered_event): Adjust call to read_char.
* lisp/cus-start.el (all): Remove inhibit-local-menu-bar-menus.

 src/xdisp.c (move_it_vertically_backward, move_it_by_lines): Don't
 use the limitation on backwards movement when lines are truncated
 in the window.

 src/bidi.c (bidi_resolve_neutral): After finding the next
 non-neutral character, accept NEUTRAL_ON type as well, because
 directional control characters, such as LRE and RLE, have their
 type converted to that by bidi_resolve_weak.  This avoids aborts
 when LRE/RLE follows a run of neutrals.
 (bidi_move_to_visually_next): Assert that return value of
 bidi_peek_at_next_level is non-negative.  Negative values will
 cause an infloop.
