I really do not think we should encourage this as a verification
method.  If you encourage it as such, I am sure people would
complain "Why can't I bypass this hook with --no-verify!!!".
I do not want to spend cycles defending the behaviour to error
out on non-zero exit from the hook.

Instead, I think you should _stress_ that people must _NOT_ use
this as a replacement for pre-commit hook.

The same comment applies to the comment in the example hook.
