    * lisp/repeat.el (repeat-mode-echo): New defcustom.
    
    (repeat-post-hook): Use it.
    (repeat-mode-message): New function (bug#47566).
    (repeat-post-hook): Use real-this-command instead of this-command
    to handle e.g. rectangle-exchange-point-and-mark remapped to
    exchange-point-and-mark (bug#47688).
