Basically, I don't object to that.  However, experience has shown that
people tend to write very sloppy git commit messages in general.  The
ChangeLog format enforces you to describe changes in a standardized
way that I consider very helpful.

If we can do what Emacs does – namely git commit messages in ChangeLog
style – I'm all for dropping direct ChangeLog entries.

This is admittedly a problem.

If you can manage to write that, please do!  Automatic formatting has
definitely benefits.  Honestly, I suggest that we get completely rid
of the special FreeType formatting.  For consistency I'm enforcing it
on all pieces of code, but virtually all contributors have
difficulties to follow the (unwritten) rules.  Something like

  int main(int argc,
           char **argv)
  {
    FT_Error error;
    FT_Library library;
    FT_Face face;
    int i;


    error = FT_Init_FreeType(&library);
    if (error)
    {
      foobar();
      die("FT_Init_FreeType failed");
    }

    if (argc != 2)
      die("no font file argument given");

    ...

looks nice IMHO – and is quite standard, AFAICS.  Of course,
vertical alignment like

    FT_Error   error;
    FT_Library library;
    FT_Face    face;
    int        i;

is quite nice, too, but I doubt that it can be really handled
automatically.

Whatever you come up with, please check whether our API documentation
can be built correctly.  Additionally, such a change should be
introduced right after a release.

Thanks, applied (with minor additions).
