bug#17286: 24.4.50; Incorrect frame height with menu-bar-mode on/off

[martin rudalics]

> Switch on/off menu-bar-mode several times:
> the frame height grows.

Thanks for the report.  I fixed this (and bug 16637 you also reported)
on my build but that's part of a larger change that won't make it into
Emacs 24.4.  If you're interested I can send you a preliminary patch.
