was going over some hooks and writing some tutorials for some of the
commit-related, client-side hooks, and was wondering (perhaps
stupidly) why the pre-commit.sample hook uses, as its last line:
exec git diff-index --check --cached $against --
^^^^^^^^^^
as in, could this not be done equivalently with just git diff, not git
diff-index? i just did a quick test and it seems to do the same thing,
but i've never taken a close look at git diff-index before so i may
just be clueless about some important distinction.
