It would be a different implementation for native menus (probably not worth 
it), Lucid, Motif/Lesstif, Nextstep and Gtk+.
Motif doesn't have a marker character, you must at the C level tell the widget 
in question which letter to use.  The Emacs C level could perhaps translate a 
marker character to this.  Gtk+ has _ as marker character, and Lucid currently 
has no keyboard handling in menus except arrow keys.
I don't know what Nextstep uses.

How do you handle buffer names (for the Buffer menu) that have the marker
character in them (& I think for W32)?  Wouldn't it be better to use a text
property at the lisp level and let each platform specific code sort this out?
