Re: menu-bar-update-hook run very often

    The doc string of `menu-bar-update-hook' states that it is a "... hook
    run for clicks on menu bar, before displaying a submenu."

I think the doc string is mistaken.  Every substantial redisplay runs
this hook since every substantial redisplay updates the menu bar
display structures (if the menu bar has changed).  For instance, it
updates the Buffers submenu if the set of buffers has changed.

I will update the documentation.  Meanwhile, do you think
the current behavior is a problem?
