Subject: bug#22581: Strange minibuffer prompt on exiting Emacs
Date: Sun, 07 Feb 2016 18:43:55 +0100

> The prompt to confirm exiting Ediff has gone a bit strange. To
> reproduce in "emacs -Q" (assuming files "x" and "y" exist in the
> working directory):
>
> M-x ediff RET x RET y RET q
>
> The expected prompt is
> "Quit this Ediff session? (y or n)  ".
>
> The actual text shown in the minibuffer is
> "Quit this Ediff session? (y or n)  switch-frame-".
>
> (The frame switch event occurred because the little Ediff control
> panel frame went away and the main frame got activated.)
>
> The "switch-frame-" is of course not really part of the prompt. It is
> rendered like what you get when you enter an incomplete key sequence,
> like "C-x-". It seems as though switch-frame is being treated as a
> prefix key, but it's not treated as such in most circumstances. Try
> this for example:
>
> C-x 5 2 ;; make-frame-command
> C-h k ;; describe-key
> ;; Use the window manager to activate the other frame.
> ;; Minibuffer prompt is "Describe key (or click or menu item):  switch-frame-")
> RET
> ;; *Help* buffer describes "RET", not "switch-frame RET".

Thanks for the report.  This is the same as bug#21797.

Bug#22068 is another instance of this.
