Added myself to the Cc: list of bug 11987 (since one of my bugs got marked as a duplicate and I didn't get added to 11987's cc: automatically... grrrr) and it triggered an email (msw@, borgan@, myself). Considering the load their mailboxes must already be under, changes like an added Cc: that don't make any real difference should NOT trigger an email if at all possible. I request this mainly because there are many bugs I'd like to add myself to the cc: of to keep track of, but triggering large amounts of useless email isn't appealing.
