Currently there is now way to do that except by modifying _path_files
(one of the reasons for how the new completion system looks was that
we wanted to give users the chance to do that).

In this case it should be enough to add another one of those `if's
around line 278 to skip over components that match `[^/]##@@/' and then 
handle them like we handle `(.|..)/' now (line 265).

Hm, I've no idea how widely used Clearcase is -- or other filesystems
that give special semantics to certain names, making globbing fail. If 
there is a cheap way to detect the use of Clearcase I could probably
be convinced to put that into the core. And if there are other uses
for a style that gives a pattern to match pathname components that
should be accepted immediatly, I could easily be convinced to add that 
(somehow that sounds useful, but I can't think of an example).
