[Message part 2 (message/rfc822, inline)]

From: Sebastian Miele <iota <at> whxvd.name>

Subject: 28.0.91; custom-prompt-customize-unsaved-options does not return nil
Date: Thu, 10 Mar 2022 17:19:07 +0100

In an emacs -Q, evaluate

  (add-hook 'kill-emacs-query-functions
            'custom-prompt-customize-unsaved-options)

  (progn
    ;; Somthing like the following may be done, e.g., by
    ;; ‘activate-transient-input-method’:
    (setq default-transient-input-method "TeX")
    (customize-mark-as-set 'default-transient-input-method))

and hit C-x C-c.  When asked about whether to examine the unsaved
options, say yes.

Expected: Emacs does not terminate, so that I can examine.

Actual behavior: Emacs terminates.

The following diff fixes this issue (and a documentation bug):

diff --git a/lisp/cus-edit.el b/lisp/cus-edit.el
