Thanks for the hint. I see now that in the old version,
%enumerate-directories didn't check to see if the directory exists.
It would just continue recursing.

A quick test shows that it's easy to restore the old behavior.
However, I have not yet tested out symlink loops.  In some ways, I
don't see why we need this check.  If you have such things on your
filesystem, you're in a bad state already.  And we have precedence for
not checking for loops since EQUALP will hang forever if you have
circular lists/structures.
