Or because xemacs already has the function so slime-DEFUN-if-undefined
does nothing.

The docstring says it returns NIL if the property is constant all the
way to the end of the object.

I hacked slime-find-note to say (goto-char (or (funcall ...)
(point-max)) and that makes things work.

And the problem with post-command-hook appears to be a bug in xemacs'
fsf compatibility function for timer-set-idle-time.  It was calling
set-itimer-restart with a second arg of t instead of the number secs.

So it looks like things are working now, except eldoc displays the elisp
function info, but slime typeout displays the correct thing.

Sorry for all trouble and messages.
