Well, it could check whether the entries are identical
and keep only the non-duplicates.

I don't think the completion behavior Dan reported can be changed at the
Info level: the low-level completion functions (e.g. all-completions)
can handle duplicates in the completion list┬╣, but the minibuffer
completion commands (e.g. completing-read) automatically discard
duplicates; so when Info-menu completes its MENU-ITEM argument, no
duplicates will be presented to the user.

The solution is that the menu items should have different names, e.g.

* Emacs: (emacs-21/emacs). The extensible self-documenting text editor. * Emacs 22: (emacs-snapshot/emacs). The extensible self-documenting text editor.

┬╣ Unless the completion list is actually a hash table or obarray, which
by definition only contains unique names.
