Correct. I seem to remember wanting to give this a test and not having access
to real perforce to try it against.

I would be very surprised, assuming that we invoke 'git hook' in the same way
that those Python and Perl scripts invoke other 'git whatever' commands...
That said, once we invoke a user hook, all bets are off as far as "we're not
starting a pager or anything". A determined user could find a reason to invoke
a pager, editor, whatever during a hook. I'm curious to know more about this
remembered breakage.
Last time I looked at the range-diff; this time I'll look at the individual
patches, instead.
Note: I looked at a bunch of these offline, so sorry for the sudden
ingress of mails today ;)
