Oh, no I was not arguing for making git crash.  I was just
trying to learn if there is a valid reason to choose to, or
common misconfiguration that causes it to, run with ac == 0,
since I did not think of any.

It is good to be extra careful and defensive -- I just wanted to
know if there is more to it.
