Ok, just drop the patch I don't feel strongly about it.

However, the code today demands that git send-email is run from within a 
git repository - it seems that $repo = Git->repository() assumes that. 
I'd suggest changing this behavior so that git send-email becomes 
runnable from outside a git repository.  Unfortunately, I'm starting to 
get in above my head here, for one I really don't know the helper 
functions in Git.pm.  Is there any good place to read up on what is in 
Git.pm, except for the code itself?
