       src/xdisp.c (move_it_in_display_line_to): Record the best matching
       position for TO_CHARPOS while scanning the line, and restore it on
       exit if none of the characters scanned was an exact match.  Fixes
       vertical-motion and pos-visible-in-window-p when exact match is
       impossible due to invisible text, and the lines are truncated.

      Speed up cursor motion in large fontified buffers. · e8c17b88
      Eli Zaretskii authored
       src/xdisp.c (reseat): Don't look for prev_stop, as that could mean a
       very long run.
       (next_element_from_buffer): When iterator oversteps prev_pos
       backwards, don't search for a new prev_stop more than 1000
       characters back.
       (handle_stop_backwards): Don't assume that CHARPOS is necessarily
       a stop_pos.
       (compute_display_string_pos): Check also BUF_OVERLAY_MODIFF for a

       applicability.

      Don't assume ptrdiff_t and EMACS_INT are the same width as int.
      In this code, it's OK to assume C99 behavior for ptrdiff_t formats
      since we're not interested in debugging glyphs with old libraries.
      * xfaces.c (cache_face): Move debugging code earlier; this pacifies
      GCC 4.6.0's static checking.

      Variadic C functions now count arguments with ptrdiff_t. · f66c7cf8

      This partly undoes my 2011-03-30 change, which replaced int with size_t.
      Back then I didn't know that the Emacs coding style prefers signed int.
      Also, in the meantime I found a few more instances where arguments
      were being counted with int, which may truncate counts on 64-bit

      * bytecode.c (exec_byte_code): Check maxdepth for overflow,
      to avoid potential buffer overrun.  Don't assume arg counts fit in 'int'.
      * callint.c (Fcall_interactively): Check arg count for overflow,
      to avoid potential buffer overrun.  Use signed char, not 'int',
      for 'varies' array, so that we needn't bother to check its size
      calculation for overflow.
