[PATCH 0/2] git-send-email: refactor duplicate $? checks into a function

A tiny series to help along the config-based hooks series[1]. Its
patch dealing with git-send-email.perl can now trivially be based on
top of this instead of adding another system() wrapper to
git-send-email.perl.

As alluded to in the TODO comment in 2/2 it's probably best to fix
things while we're at it to call validate_patch_error() instead of
just emitting the more brief "rejected by sendemail-validate hook".

But for now this series is just aiming for bug-for-bug compatibility
with the existing code, and to just reduce code duplication.
