funny filenames

[Duncan Gibson]

I had a problem on an 11/23 where the /bin had an entry for make, and another
slightly corrupt one where "od -c /bin" gave the name as
	m a k e \0 \0 \0 357 \0 \0 (etc)
Using rm zapped the proper make, and any attempts after that failed because
the dead entry for the proper make had a zero i-number. I even thought about
little prog to unlink the funny name, but since unlink expects a NULL
terminated string as a file name there was nothing to do but clri and fsck!
