FYI, Tk gets it wrong.  In Tk, if you have a binding for a sequence
like "abc" and a binding for "bc", both will fire when you type in
"abc".  I think this is hardly ever what you want, but then I'm
partial to the Emacs keymap model.

Another approach would be to have the keybinding code gloss over this
by removing low-level events it doesn't care about.  I don't know what
the real goal is, though, so I don't know if this is a good idea.

Yeah, vi requires more state than just a keymap.  So does Emacs if you
want to handle prefix arguments.

Hmm.  I hope this doesn't work by looking at the actual menu labels.
That will fail if the program uses gettext.
