That'll do surprising things when the user _really_ makes a
self-referencing symlink with "ln -s x x", which can happen
unexpectedly, for example by untarring some archive.

If a fallthrough is encoded that way, there should probably be an
error when the user tries to make a self-referencing symlink.
