We already had this once or twice (or thrice, or...). The problem is
that you sometimes want only the prefix to expand and the rest of the
line left unchanged (if the thing inside the path is ambiguous). But
unless someone modifies _match to try to keep trailing patterns that
were not substituted by matched parts, we have this -- admittedly ugly
-- behavior. I have this still lingering on my todo-list, but I'm not
sure if this could really be done (not everything is a pathname).

Btw. have you tried `compconf path_expand=yes' lately?

It can be done with _oldlist if we enhance it a bit... this is left as 
an exercise for the interested reader (at least for now ;-).

Seems I forgot to send the patch below.
