I agree. And, even otherwise, it is nice for X-Debbugs-Cc to mirror the Cc header and use a comma-separated list. So, I'm all in favour of this patch. Specific comments about the patch itself follow in a separate email. I will work on a similar patch for `mumi send-email' and send it sometime later this week. As discussed earlier, I will make `mumi send-email' invoke `git config sendemail.headerCmd' to find out about etc/teams.scm.
