bug#2984: deftype bad fontification

If you have the following Common Lisp code in a file called foo.lisp:

    (deftype foobar () "documentation" '(unsigned-byte 64))

font lock mode will display the documentation string using, I believe,
font-lock-string-face.  Instead, font-lock-doc-face should be used.
To fix the problem, look for

    (put 'defun    'doc-string-elt 3)

in lisp/emacs-lisp/lisp-mode.el and add the following line after it:

    (put 'deftype 'doc-string-elt 3)

That is, deftype should be treated just as defun or defmacro for the purpose
of fontifying the documentation string.

This bug is present in recent CVS versions of Emacs.
