I made some tests showing that it really didn't work just to put menu
bar entries in a keymap or local-map property, unless the menu-bar was
refreshed after every command, and we didn't want to do that.

Also, there was no indications of code actually using this feature, so
it was decided to take it out to prevent *new* code from using it.

I can now see that if you can ensure that the menu bar (or just the
mode line) is refreshed when point enters a text area which has a keymap
property, then it will work.  So I suppose your code does something
which triggers a mode line update.  How do you do that (I think this
is important advice for using this feature)?

In any case, I'll restore the support for menu entries in text
property keymaps ASAP!
