Agreed about the (un)parsability, and --numstat is all about parsability
so I would not object.  A fix is really needed there.

I do not have time to look at the patch right now, but if the changed
output is in line with what --name-status would show, that would be
great.  I'd call that "the format that should have been from day one".

I.e. no '=>' rename marker, but show two names c-quoted (unless -z is
used) and separated with inter_name_termination).  IIRC, that is how
rename/copy is shown with --name-status.
