These should be hopefully fixed now.  Many thanks for reading them
carefully.

Note also that in

 >>> If the frame is narrow enough to display the menu bar for current buffer
 >>> in two lines and wide enough to display the menu bar for minibuffer in
 >>> one line, toggling menu bar using minibuffer(M-x menu-bar-mode) twice
 >>> enlarges the frame height.

the term "twice" (or merely its position in the text) is misleading.
But, in fact, the bug already appears when you toggle the menu bar off
- the frame should correctly shrink in that case.

Thanks again, martin
