bug#67836: 29.1.90; map-y-or-n-p doesn't terminate when run in a kmacro


From: Spencer Baugh
Subject: bug#67836: 29.1.90; map-y-or-n-p doesn't terminate when run in a kmacro in batch mode
Date: Fri, 15 Dec 2023 10:38:47 -0500

1. Create a file "broken.el" containing:
(defun broken ()
  (map-y-or-n-p ""  #'ignore '(1)))
(execute-kbd-macro (read-kbd-macro "M-: (broken) RET"))
2. emacs -Q -l ./broken.el
3. Emacs properly executes the keyboard macro and errors.
4. emacs -Q --batch -l ./broken.el
5. Notice Emacs infinite loops, printing the map-y-or-n-p prompt repeatedly.

map-y-or-n-p in a keyboard macro terminates in non-batch Emacs because
it calls (ding), which terminates the currently running keyboard macro.
However, (ding) doesn't terminate keyboard macros in batch mode.  This
seems to just be an oversight.

A patch to fix this by making (ding) always terminate keyboard macros
will follow.

(BTW, when not running in a keyboard macro, map-y-or-n-p will error in
batch Emacs, but only because of a separate bug where it runs (listp
last-nonmenu-event) to decide whether to use menus, which returns true
since last-nonmenu-event is nil.  I may fix this separately.)
