[drew.adams@oracle.com: \\{...} produces duplicate entries]

It would be good to fix this for later installation.

emacs -Q

(defun toto () "\\{minibuffer-local-completion-map}"  4)

C-h f toto shows a duplicate entry for C-=:

toto is a Lisp function.
(toto)

Only a single C-= entry is present in Emacs 20 and Emacs 21.

Actually, the bug is already present in Emacs-20.  It's just that in
Emacs-22, we have remove the duplication of bindings between
minibuffer-local-completion-map and minibuffer-local-map by making the first
inherit from the second.  If that same ineritance is added to Emacs-20, the
same bug will manifest itself.

This said, it should be fixed, of course.
