Thanks. That looks like a useful addition. Could you try and make it
an actual patch (as output by `diff' and friends), also could you also
make sure your code uses a proper prefix ("lisp-") for all the functions
it defines, and finally could you make sure it's only enabled when it's
useful (I don't think we support such :documentation thingies in Elisp
(tho maybe EIEIO does) so it should only be enabled in lisp-mode but
not in emacs-lisp-mode).
There's time for that: we're in feature freeze for Emacs-24.1, so we
won't install such a change before early next year.
