It helps, but also seems to cause a regression.  With this change I get:

1. emacs -Q
2. Insert "(cond ((current-p"
                  ^note the additional parenthesis
3. Hit M-TAB to complete

This shows an opposite bug: Emacs should complete function names (and
without the change, it does), but with the change we now get variable
name completion.


Thanks,
