Great key rebinding.

  * Rebind Enlightenment keys to use right-hand Alt key, leaving left
    Alt available for Emacs.

  * Remove a bunch of old Emacs key bindings.  In particular, F9
    (`mdw-divvy-window') is now on C-x w d; `undo' is removed from F8
    and is now only (ahem) on C-x u, C-_ and C-/.  F4
    (`query-replace-regexp') moved to the default C-M-%.  F5
    (`goto-line') is on M-g M-g.  F6 (`auto-fill-mode') is moved to
    C-x /.  Finally, M-RET is no longer `kmacro-call-macro', but one can
    use C-x C-k C-k or (now we've stopped squatting on it) F4.

The remaining fly in the ointment is that C-M-DEL is still trapped by
the X server.  This needs some XKB hacking.
