Before you break your head over trying to understand why the code works,
here are a few notes (if you are training for the obfuscated shell contest,
don't read on):

The -c option makes sure all nodes exist, even if the glob is failing.  So
you might end up with empty files like '*' or '.??*'.

local variables are not supported by POSIX.  We get away with using a
recursive function anyway because it is mostly tail recursive.  The only
problem is the "rmdir $f", which comes after the recursion and uses a local
variable.  The dirname $f makes up for this case, because the only thing
that happens after the recursion is that $f has a path element more than
before.

It is black magic, but it seems to work :)

Thanks,
Marcus
