bug#14546: 24.3.50; semantic/bovine/el.el + return value of `which-funct

I see that when Emacs lisp files are parsed by semantic, the return
value of `which-function' has extra decorations. 

1. Put the below snippet in your .emacs
2. emacs -Q
3. Examine *Messages* buffer. You will see

     {declare-function}
     (find-file)

   The `{}' and `()' are what I call decorations.  

4. Comment  `load-library' line in .emacs. Restart emacs.
5. You will see

     ;; null-device
     ;; find-file


Semantic intelligently identifies the `declare-function' rightly while
Emacs naively identifies a preceding `defvar'.  (Thumbs up for semantic
parsing)

But, please clarify how to interpret the extra decorations (or remove
them if they are spurious).
