I don't think that the match-all pattern modifier works as can be
expected from a logical point of view.
The attached patch will make it work as I expect it to work:
- It works on all patterns which explicit or implicit use address
lists: ~c, ~C, ~e, ~f, ~l, ~L, ~p, ~P, and ~t. (It didn't work
with ~l before).
- It works such that a modified pattern always match, unless there
is at least one address in at least one of the referenced lists
that it doesn't match.
