Nope, it's not a beginning-of-line (or of string) for `^' to match.

But there are messages that are posted to multiple mailing lists, and
I'd receive multiple copies of the message with different
Sender/X-loop/whatever headers.  If I relied on them, I'd have to
disable discarding of duplicates, which I don't want to do, or I'd
have to live without cross-posting.

Anyway, my particular problem doesn't matter much; the fact is that
there's no way to make sure you're not getting the implicit .* to
match a `-' you don't want it to match.  Although it is nice to have
full words by default, `-' is a word separator, so it doesn't always
get it right.

Precisely.

Nope, I don't want cross-posting where it doesn't belong, i.e., if a
message was only posted to bug-libtool-owner, it shouldn't appear in
the libtool group.
