 +
 +      * insdel.c (insert_from_gap): New arg text_at_gap_tail.
 +      (adjust_after_replace): Make it back to static.  Delete the third
 +      arg text_at_gap_tail.  Cancel the code for handling it.
 +
 +      * coding.h (struct coding_system): New member eol_seen.
 +
 +      * coding.c (detect_ascii): New function.
 +      (detect_coding): Set coding->head_ascii and coding->eol_seen only
 +      when the source bytes are actually scanned.  On detecting for
 +      coding_category_utf_8_auto, call detect_ascii instead of scanning
 +      source bytes directly.
 +      (produce_chars): Call insert_from_gap with the new arg 0.
 +      (encode_coding): Likewise.
 +      (decode_coding_gap): Control ASCII optimization by the variable
 +      disable_ascii_optimization instead of #ifndef .. #endif.
 +      Deccode EOL format according to coding->eol_seen.
 +      (syms_of_coding): Declare disable-ascii-optimization as a Lisp
 +      variable.
 +
 +      * global.h (struct emacs_globals): New member
 +      f_disable_ascii_optimization.
 +      (disable_ascii_optimization): New macro.
 +
 +      * lisp.h (adjust_after_replace): Cancel externing it.
 +      (insert_from_gap): Adjust prototype.

+ 2013-03-15  Eli Zaretskii  <eliz@gnu.org>
+ 
+       * w32term.c (w32fullscreen_hook): Swap FULLSCREEN_BOTH and
+       FULLSCREEN_MAXIMIZED.  (Bug#13935)
+ 
+ 2013-03-15  Dmitry Antipov  <dmantipov@yandex.ru>
+ 
+       * region-cache.c (find_cache_boundary, move_cache_gap)
+       (insert_cache_boundary, delete_cache_boundaries, set_cache_region):
+       Simplify debugging check and convert to eassert.  Adjust comment.
+       (pp_cache): Put under ENABLE_CHECKING.
+ 
+ 2013-03-14  Eli Zaretskii  <eliz@gnu.org>
+ 
+       * w32term.c (w32_read_socket) <WM_WINDOWPOSCHANGED>: Remove old
+       and incorrect code.  Treat WM_WINDOWPOSCHANGED like WM_ACTIVATE
+       and WM_ACTIVATEAPP.
+       (w32fullscreen_hook): If the frame is visible, reset
+       f->want_fullscreen flag after changing the frame size.  If the
+       frame is not visible, set f->want_fullscreen to FULLSCREEN_WAIT.
+       (Bug#13953)
+ 
+ 2013-03-13  Daniel Colascione  <dancol@dancol.org>
+ 
+       * emacs.c (main): Call syms_of_cygw32 on CYGWIN non-NTGUI builds
+       too so that these builds can use Cygwin's file conversion
+       functions.  (We've been building and linking cygw32.o all along
+       and just not using it.)
+ 
+ 2013-03-13  Paul Eggert  <eggert@cs.ucla.edu>
+ 
+       File synchronization fixes (Bug#13944).
+       * Makefile.in (LIB_FDATASYNC): New macro.
+       (LIBES): Use it.
+       * conf_post.h (BSD_SYSTEM, BSD_SYSTEM_AHB): Remove; no longer needed.
+       * fileio.c (Fwrite_region, write_region_inhibit_fsync):
+       Don't worry about HAVE_FSYNC, since a substitute fsync is
+       available if the system lacks one.
+       (Fwrite_regin): Retry fsync if interrupted.
+ 
+ 2013-03-13  Eli Zaretskii  <eliz@gnu.org>
+ 
+       * w32term.c (w32_read_socket): If the Emacs frame is being
+       activated, call w32fullscreen_hook, to make sure the new frame
+       dimensions are in effect.  (Bug#13937)
+ 
+ 2013-03-13  Dmitry Antipov  <dmantipov@yandex.ru>
+ 
+       * xdisp.c (init_iterator): Simplify because both character and byte
+       positions are either specified or -1.  Add eassert.  Adjust comment.
+       * window.c (Fscroll_other_window): Use SET_PT_BOTH because both
+       character and byte positions can be obtained from marker.
+ 
+ 2013-03-13  Paul Eggert  <eggert@cs.ucla.edu>
+ 
+       Static checking by Sun C 5.12.
+       * alloc.c (buffer_memory_full) [REL_ALLOC]:
+       * bytecode.c (exec_byte_code):
+       * dispnew.c (init_display):
+       * eval.c (error):
+       * fileio.c (Fsubstitute_in_file_name):
+       * keyboard.c (Fevent_convert_list):
+       * keymap.c (Fsingle_key_description):
+       * term.c (maybe_fatal, fatal):
+       * xfns.c (Fx_display_backing_store, Fx_display_visual_class):
+       * xsmfns.c (Fhandle_save_session):
+       Omit unreachable code.
+       * keymap.c (map_keymap_char_table_item): Cast void * to
+       a function pointer type; the C Standard requires this.
+ 
+       * sysdep.c: Remove a use of BSD_SYSTEM, which I'm trying to phase out.
+       Include <sys/param.h> unconditionally, as that works elsewhere and
+       is simpler here.  Include <sys/sysctl.h> if DARWIN_OS ||
+       __FreeBSD__, not if BSD_SYSTEM, since it's needed only for Darwin
+       and FreeBSD now.
+ 
  2013-03-11  Paul Eggert  <eggert@cs.ucla.edu>
  
        * insdel.c (adjust_after_replace): Use bool for boolean.
