(that binding is currently shadowed ...)

[Lennart Borgman (gmail)]

If cua-mode is enabled and you define a minor mode using C-c as a prefix 
key you describe-bindings wrongly says that C-c is shadowed. This is 
quite disturbing since C-c by some of the punctuation characters is what 
a minor mode is supposed to use (my example uses C-c RET which is a bit 
bad). Here is how the output can look:

key             binding
---             -------

C-c             Prefix Command
  (that binding is currently shadowed by another mode)

C-c RET         Prefix Command


Here is an example to use to reproduce it. Start with

   emacs -Q
   M-x cua-mode

Then eval the code below and do

   M-x mlinks-mode
   C-h f mlinks-mode RET

(defvar mlinks-mode-map
  (let ((m (make-sparse-keymap)))
    (define-key m [(control ?c) ?\r ?\r] 'mlinks-goto)
    (define-key m [(control ?c) ?\r ?n]  'mlinks-next)
    (define-key m [(control ?c) ?\r ?p]  'mlinks-prev)
    (define-key m [(control ?c) ?\r ?h]  'mlinks-toggle-highlighter)
    m))

(define-minor-mode mlinks-mode
  "
\\{mlinks-mode-map}
"
  nil
  " ML"
  nil
  :global t
  :keymap mlinks-mode-map
  :group 'mlinks)
