I was terribly confused as to why i'd been demoted to third-person
status until i noticed that this bounced over to developers@ (i proc all
my bugzilla mail to a single folder).

Joel pointed me to https://bugzilla.mozilla.org/show_bug.cgi?id=204903.
I'm waiting on an alluded-to-but-not-in-the-bug final patch for this.

How would the NOT operator be different from "doesn't match regexp"?

Also, everything =~ /./ (except, evidently, the null that QA
Contact has by default), so why would !~ /./ be helpful?
