a passable first approximation, but not a final solution.

As I mentioned immediately after asking the question, this method will
identify an empty directory as a file.

e.g. if the list of directories & filenames to be processed contains
an empty directory called, for example, /usr/lib/whatsit then your
algorithm will incorrectly identify it as a file.

Dirk came up with a neat generic solution to the question using perl.
