Two identical filenames in one directory!

[John Nagle]

      Does FSCK validate filename syntax?  If it doesn't, it's a bug in
FSCK; one should be guaranteed that once a file system passes FSCK, it is
in a valid state.

      I've been at this too long.  I fixed the comparable bug in 1975
in CATFR (Catalogued File Recovery) in the Exec 8 operating system for 
UNIVAC mainframes.
