Well, I think we have two options here. The first is to extend
--directories with a new option "skip-symlinks", which skips all
symlinks to directories. The second would be to keep a list of
(fsid, inode) from all the directories already processed. That
would be the full loop detection, but can slow down the processing
a lot.
