   [test case?]

thanks for looking into this.

below is a script (write to /tmp/z ; chmod +x) that shows little output
and exit code 0 with the patch and spurious "0 files changed" and exit
code 1 without.  i am curious how it behaves w/ other versions of git.

fyi, to simulate "without patch", i actually used the small mod:

  if (! total_files, 0)

which produced a compiler warning (of no consequence).
