Well, it *could* be confusing the NoDups code (if that code contains a bug).

I'm not good enough at reading RFC 2822 to know whether a blank Cc: header
is legal or not (after spending only a few minutes, I lean toward not
legal), but either way having such a header mess up NoDups processing would
be a Mailman bug.

A test here with Mailman 2.1.2 seems to say that a blank Cc: header doesn't
bother the NoDups processing in that version.  (Where "blank" means either
just a space after Cc: or nothing after Cc:)  (Test run using telnet to the
mail server by hand.)
