+        * emacs-lisp/easy-mmode.el (define-minor-mode): Add extra
+        parameter "after-hook:" to allow the expansion to run code after
+        the execution of the mode hooks.
+
+        * font-lock.el (font-lock-initial-fontify): New function extracted
+        from font-lock-mode-interal.
+
+        * font-core.el (font-lock-mode): call font-lock-initial-fontify in
+        :after-hook.
