    Case in point is the buffers menu.  If you happen to have a buffer with an 
    underscore in the name, it wouldn't be correct when making the menu entry.

Yes, we would need a Lisp-level way to turn off the mnemonics feature.
It could be done at the level of menu items, or it could be done at
the level of a whole menu.
