Fix bug with forced links not working in all cases 

This commit fixes a bug where forced links did not work on certain types
of bad links. Until this fix, forced links only worked if the original
was a real file or directory. This commit fixes this, so that the forced
link option also works when the original is a broken or incorrect
symbolic link.
