The thing is, though, it isn't really descending.  The path may not
even exist.  It's just moving from left to right through a bunch of
tokens, which may or may not correspond to a real filesystem.  If it
were really a full traversal, you'd get:

   a
   a/b
   a/b/c
   a/b/c/d

*plus* whatever else branched off of b, c, and d.

whereas what we're talking about here, as I understand it, is:

   a
   b
   c
   d

which is much more just a list of components than a recursive traversal.
