Well, would this work?  "\\(^\\|.*[< ,]\\)libtool@gnus\\.org"

I think you're using the wrong approach, though.  Most mailing lists
contain a header which uniquely idenfies the mails.  Often, the header
is X-Loop, but the Sender header can also often be used.

Hm.  How does one match "Sender: foo-owner@frob.org" exactly with
fancy splitting?  Maybe it's not so easy after all :-(

Yet another approach would be to split on the first match only, to
check for bug-libtool first, but to give two groups if this matches.
Lessee...

(| ("Sender" "bug-libtool-owner" (& "bug-libtool group" "libtool group"))
   ("Sender" "libtool-owner" "libtool group"))

[time passes]

Oh!  The header is "owner-libtool" rather than "libtool-owner", so it
is trivial to match "owner-libtool" but not "owner-bug-libtool".

Just my two cents.
