Should semantic work in emacs lisp buffers? I noticed that stickyfunc-mode was not putting the defun name at the top of the buffer. 

Comparing with other modes, I found that semantic-default-elisp-setup exists and should do some setup.  However, it is an empty defun.

Am I missing something?  Is there a simple way to turn this on?

I am using Emacs 24.3 with the built-in CEDET:

GNU Emacs 24.3.1 (i686-pc-cygwin, GTK+ Version 3.8.2)
