Okay, that seems in line with a hook such as pre-commit. Please do
update the documentation to mention that the hook takes no arguments
and nothing on standard input, and perhaps describe in the
documentation an example use-case (as you did here).

I'm not a p4 or git-p4 user, but, out of curiosity, would there be any
information which could be supplied to the hook as arguments or
standard input (or both) which would help the hook author implement
the hook more easily? Perhaps such information would be fodder for a
future enhancement (not necessarily needed for this patch).

This might be a good thing to add to the documentation, as well.

Following existing practice makes sense. It can always be revisited
later if needed.

Thanks.
