Don't use $author_name undefined when $from contains no /\s</.
I noticed a case not handled in a recent patch. Demonstrate it like this: $ touch new-file $ git-send-email --dry-run --from j --to k new-file 2>err new-file OK. Log says: Date: Thu, 19 Oct 2006 10:26:24 +0200 Sendmail: /usr/sbin/sendmail From: j Subject: Cc: To: k Result: OK $ cat err Use of uninitialized value in pattern match (m//) at /p/bin/git-send-email line 416. Use of uninitialized value in concatenation (.) or string at /p/bin/git-send-email line 420. Use of uninitialized value in concatenation (.) or string at /p/bin/git-send-email line 468. There's a patch for the $author_name part below. The example above shows that $subject may also be used uninitialized. That should be easy to fix, too.
