This change makes menu entries that differ only in case different.
For example, AUCTeX has a "Greek" and a "greek" menu.  More
importantly, it has menu entries
γ \gamma
and
Γ \Gamma
and those now get differentiated again (though their names now get
swapped).

Menus that differed only in case were already given different names in
21.3.  Smudging them together only occured because of Richard
downcasing the menu names (with easy-menu-intern) at some time during
21.4 development.

What does your code do that did not already break in Emacs 21.3?

The new behavior is certainly no bug: it is entirely easymenu's choice
what symbols to use for some menu, that's some internal decision.  I
can't rule out, however, that maybe easy-menu-intern is used in more
or less places than required, which could cause such mismatches.

Can you go into details about the usage patterns that cause this
problem?  If they do not have similar problems with Emacs-21.3
already, there might be some bug.

It should not be tampering with internals.  If your problem is not due
to that, you should provide examples of what happens.
