Subject: bug#22000: Patch addressing the menu-bar frame-resize interaction

I see.  Making the default emacs -Q frame narrow enough so the Help
menu entry is not showing, maximizing and demaximizing that frame
shows the Help menu again.

Then I'm at my wits' end.  Please devise a new option like, for
example, 'gtk-menu-bar-no-auto-resize' and condition execution of your
code on the value of that variable.  And please explain the trade-offs
in the doc-string of that option and that the option may be removed in
the future.  Otherwise, people might claim that they do like the
auto-resizing in the unlikely case that we do find a better solution.
And we eventually have to document this in the manuals.

Thanks again for all the work, martin
