The following code demonstrates this bug involving parent keymaps:
;; The parent keymap binds key sequence "a b"
;; (making "a" a prefix key with a submap).
(defvar my-keymap-parent
(let ((map (make-sparse-keymap)))
(define-key map (kbd "a b") 'foo)
map))
;; The child keymap binds a command directly to "a" meaning
;; that the parent's submap is not accessible from the child.
(defvar my-keymap-child
(let ((map (make-sparse-keymap)))
(set-keymap-parent map my-keymap-parent)
(define-key map (kbd "a") 'bar)
map))
;; However (describe-keymap 'my-keymap-child) displays the "a b"
;; binding as if it were a useable key sequence:
Key Binding
------------------------
a bar
a b foo
I think that this output should only show the "a" binding.
