A recent commit (dec 2009) seems to have changed the behavior of wild-inferiors.
Prior to the change :wild-inferiors would match 0 or more pathname components. After the change 1 or more.

e.g.

(TRANSLATE-PATHNAME #P"IDO:IMMUNOLOGY;" #P"IDO:IMMUNOLOGY;**;*.*" #P"/Users/alanr/repos/infectious-disease-ontology/trunk/src/ontology/**/*.*")

Used to work, but now fails.

    Unsupported case in TRANSLATE-DIRECTORY-COMPONENTS.
