If I invoke Dired with an explicitly qualified wildcard like
OZ:KANSAS:<COMMON>META*.*.*, and then later return to that Dired buffer
and type c-X D, it lists <COMMON>*.*.* (note the "META" is gone).  I
would like it to use the same wildcard it was originally invoked with
(which it certainly knows, because it's on the top line of the buffer).
