After looking around some more, I think if graphic-char-p is T, then
we aren't required to have a name.  So I think this test should really
be:

(check-for-bug :characters-without-good-names
  (let ((wrong-codes nil))
    (dotimes
        (code char-code-limit)
      (let ((c (code-char code)))
        (unless (or (graphic-char-p c)
		    (eql c (name-char (char-name c))))
          (push code wrong-codes))))
    (nreverse wrong-codes))
  NIL)

But perhaps the intent here is that you really WANT names for all
characters, in which case, the original is ok.
