That could be a bug in TTY menus, or maybe a side effect of how the
menu bar is displayed there.
AFAICT, the duplicate menu is the consequence of the fact that
edebug-mode has its keymap inherit from emacs-lisp-mode:
(defvar-keymap edebug-mode-map
:parent emacs-lisp-mode-map
So when Edebug is activated, it wants to display yet another "Emacs
Lisp" menu on the menu bar.
Stefan, do you see a way to avoid that?
Or maybe we should not consider this a bug at all? After all, what's
the damage?
