Hmm, I am not sure what you mean by this.  If the pathspec says a/b*/c,
you are in "a" and are deciding if you should descend to its subdirectory,
then you would surely want to be able to say:

 (1) Ah, the subdirectory I am looking at is "bar" and it does match "b*".
     It might contain "c"; I should descend into it.

 (2) Nope, the subdirectory I am looking at is "frotz" and it can never
     match "b*", so there is no point recursing into it.
