Thanks for the reply, Martin.  You're quite right that closing the buffer
causes help invocation to display the menu again.

Doesn't anyone know of a solution to avoid using the disambiguation pop-up
window when invoking help on a multiply defined function name?  Emacs is all
about not having to use a mouse, so it's kind of disappointing to have to
respond to a pop-up window.
