A bigger question is why is this change desirable? What is the
justification for turning this into an error and possibly breaking
existing automation scripts? Arguing that this case should be an
"error" is difficult considering that there are many other commands
(inside and outside of Git) which exit with 0 when they have nothing
to do. I can't find the message in the archive right now, but I recall
a few months ago Junio shooting down an analogous change to some other
command, so the justification needs to be a strong one.

Also, your Signed-off-by: is missing. See
Documentation/SubmittingPatches.  Thanks.
