Re: [PATCH 7/9] hook: allow out-of-repo 'git hook' invocations

Since hooks can now be supplied via the config, and a config can be
present without a gitdir via the global and system configs, we can start
to allow 'git hook run' to occur without a gitdir. This enables us to do
things like run sendemail-validate hooks when running 'git send-email'
from a nongit directory.

It still doesn't make sense to look for hooks in the hookdir in nongit
repos, though, as there is no hookdir.

Hrm, I haven't tested but re the discussion we had about
RUN_SETUP_GENTLY on my re-rolled base topic is this really just a
regression in my changes there?

I.e. I assumed we could do RUN_SETUP for the bug-for-bug compatibility
step, but send-email runs out of repo hooks and we just didn't have
tests for it, or am I missing something?
