-This tries to keep symlink loops from happening when using
-the --copy-links option (on the sender) and when using the
---keep-dirlinks option with --delete (on the receiver).  It
-would be nice to improve this so that duplicates get turned
-back into symlinks, but the code needs to know which one is
-the real dir (if it is present in the list) because that one
-entry can't be turned into a symlink.
