[expert] Recursive symlinks in /usr/bin?

[Tom Eastman]

[tom@celleste bin]$ ls -ld /usr/bin/mh
lrwxrwxrwx    1 root     root            1 Dec 29  2000 /usr/bin/mh -> ./   



Why is there a symlink in /usr/bin called mh which points straight back to /usr/bin???

Is this kind of recursive symlink a bad thing?  or can I just ignore it?
