[cmucl-imp] format-related warning

[Didier Verna]

  Hello,

I just discovered a small bug in a format string of mine thanks to CCL. 
It is illustrated below: the ~:; control sequence is meaningless in this
context.

(defun test ()
  (format t "~:[[~A]~:;~A~]" t "foo")
  (format t "~:[[~A]~:;~A~]" nil "bar")
  (values))

This function still works correctly, but perhaps a warning would be nice
to have, as CCL does.
