Small `c-electric-paren' fix

[David Hansen]

Hello,

I've already send this to the cc-mode list some time ago (X-Post
anyway) but seems the maintainer is kinda busy.  Can someone else
please take care of it?  It's clearly a bug and the fix is pretty
short and obvious.

To reproduce:

(defun dh-c-mode-hook ()
  (push 'space-before-funcall c-cleanup-list))

(add-hook 'c-mode-hook #'dh-c-mode-hook)


Now open some .c file and type some parenthesis.  A space is
automatically inserted even if the paren is not a function call.

Fix:
