`yes-or-no-p' eventually winds up calling read_minibuf which does

   if (minibuffer_auto_raise)
     Fraise_frame (mini_frame);
   ...
   if (!EQ (mini_frame, selected_frame))
     Fredirect_frame_focus (selected_frame, mini_frame);

`y-or-n-p' instead does

                     (when minibuffer-auto-raise
		      (raise-frame (window-frame (minibuffer-window))))
		    ...
		    (redirect-frame-focus (window-frame (minibuffer-window)))

which strikes me as incongruent with the former since IIUC the last form
only redirects the minibuffer-window frame's focus to itself.  If this
is not the intended behavior, a possible source of the bug is that the
second argument of `redirect-frame-focus' is not mandatory.  As a
consequence, authors (including me) tend to consider its first argument
reference the frame that shall be focused.
