This turned out to be a problem with WILD-PATHNAME-P not detecting wildcards in components which were string (i.e. (WILD-PATHNAME-P "foo*bar") was returning nil), which I have fixed in [r12667][1] for "*" occuring in DIRECTORY, NAME, and TYPE string components.  The rules for HOST and DEVICE would be a little more complicated, which I don't have time at the moment.

This is identical to  the algorithm implemented in
Pathname.java:match-wild-jar-pathname (I think I aped your
implementation into Java).  I had coded a further check that the argument was
indeed a wild pathname, which was failing due to a faulty WILD-PATHNAME-P
