[PATCHv2 07/15] format-patch: use default email for generating message ids

From
Jeff King <peff@peff.net>
Date
May 21, 2012, 23:10 UTC
Message-ID
<20120521231008.GG10981@sigill.intra.peff.net>

<20120521230917.GA474@sigill.intra.peff.net>

We try to generate a sane message id for cover letters and threading by appending some changing bits to the front of the user's email address. The current code parses the email out of the results of git_committer_info, but we can do this much more easily by just calling ident_default_email ourselves.
