hexl-mode's offer to "Convert contents back to binary format?" doesn't

[Chris]

$ emacs -Q
M-x shell RET
cd /tmp RET
echo hello > file RET
C-x 4 f file RET
M-x hexl-mode RET
C-x o
echo world >> file RET
C-x 4 f file RET
  ("File file changed on disk.  Reread from disk? (yes or no)")
yes RET
  (notice the contents of buffer 'file' are now in plain text, but the
   buffer is still in hexl-mode)
  ("Convert contents back to binary format? (y or n)")
y

buffer 'file' is now in fundamental mode and contains one line:

------------------------------------------------------------------------
00000000: 83                                       .
------------------------------------------------------------------------

So Emacs has inserted the plain file contents into a hexl-mode buffer,
and then offered to unhexlify them.
