Yeah, that's the problem.  I'm not sure how to solve this.  When you
send to, say, 4957-quiet@debbugs, the mail header looks like this:

  Received: from localhost ([127.0.0.1] helo=debbugs.gnu.org)
        by debbugs.gnu.org with esmtp (Exim 4.69)
        (envelope-from <debbugs-submit-bounces@debbugs.gnu.org>)
        id 1ND2YX-0003mO-6P
        for submit@debbugs.gnu.org; Tue, 24 Nov 2009 16:04:13 -0500
  Received: from fencepost.gnu.org ([140.186.70.10])
        by debbugs.gnu.org with esmtp (Exim 4.69)
        (envelope-from <rgm@gnu.org>) id 1ND2YW-0003mJ-En
        for 4957-quiet@debbugs.gnu.org; Tue, 24 Nov 2009 16:04:12 -0500

Based on the last "for 4957-quiet@debbugs.gnu.org" line, the script
knows that the email was sent to 4957-quiet prior to going to the
moderation list.

When you send to 4957-quiet@debbugs and BCC control@debbugs, the headers
get stripped out:

  Received: from localhost ([127.0.0.1] helo=debbugs.gnu.org)
	by debbugs.gnu.org with esmtp (Exim 4.69)
	(envelope-from <debbugs-submit-bounces@debbugs.gnu.org>)
	id 1ND1u8-0003Wd-24
	for submit@debbugs.gnu.org; Tue, 24 Nov 2009 15:22:28 -0500
  Received: from fencepost.gnu.org ([140.186.70.10])
	by debbugs.gnu.org with esmtp (Exim 4.69)
	(envelope-from <rgm@gnu.org>)
	id 1ND1u7-0003WT-AY; Tue, 24 Nov 2009 15:22:27 -0500
  Received: from rgm by fencepost.gnu.org with local (Exim 4.67)
	(envelope-from <rgm@gnu.org>)
	id 1ND1u3-0004qm-49; Tue, 24 Nov 2009 15:22:23 -0500

I don't know why this happens, but unless someone can think of a fix, it
seems we have to either give up the practice of using BCC to manipulate
bugs, or abandon moderation via mailing list.  Thoughts?
