Oh, right it's not what I thought.  Yes, it's a bit inconvenient to move
the mapping from C-mouse-3 to mouse-3 because you really want to put
onto mouse-3 the menu-item that's on C-mouse-3, but

(global-set-key [down-mouse-3] (key-binding [C-down-mouse-3]))

will only give you the keymap returned by mouse-menu-major-mode-map
rather than the menu-item itself.  You'd like to be able to do:

  (global-set-key [down-mouse-3] [C-down-mouse-3])

But that doesn't work because such remapping don't work right for events
with parameters such as mouse clicks.  I guess you can do:

  (global-set-key [down-mouse-3] (cdr (assq 'C-down-mouse-3 global-map)))

but it's ugly.  Maybe we need a way to ask `key-binding' to return
menu-items rather than the binding specified in them.  But key-binding
already takes many parameters..maybe we could abuse the `no-remap' arg
for that?
