We are all waiting for inclusion of Cedet to Emacs, but I want to note
that Isearch in Emacs now has much cleaner infrastructure for searching
function names, where everything is necessary to do is just to define
a hook like:

(set (make-local-variable 'isearch-success-function)
     (lambda (mb me)
       (save-match-data
	 (let ((re (cdr (assoc nil imenu-generic-expression))))
	   (and (save-excursion (beginning-of-line) (looking-at (car re)))
		(>= mb (match-beginning (cadr re)))
		(<= me (match-end (cadr re))))))))

The only problem is to find a good keybinding to start function name isearch.
Maybe take the same keybinding as used by Senator, or the same keybinding used
by Dired filename isearch `M-s f C-s' where `f' could mean `function name'?
