Subject: bug#71654: [PATCH] Fix display-buffer-override-next-command
Date: Wed, 19 Jun 2024 12:20:19 -0300

[Message part 1 (text/plain, inline)]

When display-buffer-overriding-action's car is set to a function instead of
a list, display-buffer-override-next-command must ensure that the car is a
list before pushing a new element to it, otherwise the car will become a
itself a cons-cell and the clear-fun will trigger a wrong-type-argumen
error when trying to delq the action.

The error can be triggered by using some minor mode that
updates display-buffer-override-next-command (such as purpose-mode) and
then calling other-window-prefix.

The patch was created using the `emacs-29` branch.
