Piping the output of git commands like git-ls-files to another
command (grep in this case) hides the exit code returned by
these commands. Prevent this by storing the output of git-ls-files
to a temporary file and then "grep-ping" from that file. Replace
grep with test_grep as the latter is more verbose when it fails.

Looks good. Will queue with two instances of a minor style fix (see
below).

Redirection operator ">" and "<" sticks to the file in question
(look for "> " and "< " in this file and you'd find none), i.e.
git ls-files -s file >ls-files-output &&
Thanks.
