Here's a *very* experimental patch that handles separators in a totally 
different way. Instead of removing duplicates, this *inserts* separators 
between different sections of the context menu. This works by giving 
menu items a `:section' property, and if that changes (and both the old 
and new section names are non-nil), the code inserts a separator between 
the two items.

This patch only really works for elisp-mode using the default context 
menu functions, since I didn't want to spend too much time updating 
everything for a small experiment. It shouldn't be terribly hard to 
update all the other context menu functions if we decide to go with 
something like this though.

This strategy seems less brittle from my experiments so far, since we no 
longer have to be so careful about getting the order of the keys exactly 
right in order to be able to detect the duplicated separators. It also 
makes it easier to insert duplicated separators if that's really what 
you want.
