bug#4357: 23.1.50; local mode menus empty or supplanted

Here, the Emacs-Lisp menu at the top of the screen is OK:
$ emacs-snapshot -q /tmp/x.el
But here,
$ emacs-snapshot -q
C-x C-f /tmp/x.el
it is empty!!

Seems to happen also to other local modes too, and with
M-x w3m, the w3m menu gets some weird lisp mode commands instead of its
own.

However, throughout all cases, tmm-menubar is OK.
