[PATCH 7/7] format-patch: do not use bogus email addresses in message ids

[Jeff King <peff@peff.net>]

We can ask git_committer_info to be strict about coming up
with an email, which will die automatically on a poorly
configured machine. This is better than letting invalid
message-ids into the wild.
