outline-regexp) using ";; *+ " for elisp code

[Christopher Dimech]

You are right, setq-local does not take effect.  How does defvar solve the 
problem?

   (setq-local rgc ";;; \\*+ ")

   (add-hook 'emacs-lisp-mode-hook
             (lambda ()
               (set (make-local-variable 'outline-regexp) rgc)))
