$ cat report.txt
  nil

C-h v mentions no change.  Fortunately there are not too many changes to
buffer.c

    Avoid grave accent quoting in stderr diagnostics
    
    A few Emacs diagnostics go directly to stderr, and so can't easily
    contain curved quotes (as non-UTF-8 locales might mishandle them).
    Instead of bothering to add support for this rarity, reword the
    diagnostics so that they don't use grave accent to quote.

    * src/unexmacosx.c (unexec):
    * src/xfns.c (select_visual):
    * src/xterm.c (cvt_string_to_pixel, x_io_error_quitter):
    Reword stderr diagnostics to avoid quoting `like this'.
    * src/unexmacosx.c: Include errno.h.
    * src/xfns.c (select_visual): Encode value for locale.

    Remove format2

    It is more trouble than it's worth, now that we have CALLN.

    Adjust to format2 going away.

The stable Emacs version I've got is 24.5. Why is Org git trying to pull
it in when exporting if it doesn't exist?  Probably I missed something.
