[PATCH 1/1] completion: don't comp revs when --no-format-patch

["Britton Leo Kerin" <britton.kerin@gmail.com>]

In this case the user has specifically said they don't want send-email
to run format-patch so revs aren't valid argument completions (and it's
likely revs and dirs do have some same names or prefixes as in
Documentation/MyFirstContribution.txt 'psuh').
