Re: Multiple runs of menu-bar-update-hook

[Richard Stallman]

    Is this the kind of debugging you wanted - does it help?

It is the right kind, and it gives some useful info.

Now the question is, since it ran the hook inside update_menu_bar,
why did it run the hook again in set_frame_menubar?
Something near the start of that function must be setting deep_p
to nonzero.  Can you see what it is, and why?
