It's quite rare to see a non git generated diff these days.

I frequently do 'git show $commit | scripts/checkpatch.pl' and this
doesn't work with that. I really should have a '--pretty=email' in
there, but I just ignore the commit msg warnings. In any case, that
still doesn't help because there's no diffstat. There's probably some
way to turn that on or just use git-format-patch, but really we want
this to work with any git diff.
