Subject: bug#77966: 30.1; Text wrongly displayed with font-lock-warning-face
Date: Mon, 21 Apr 2025 18:03:35 +0100
[Message part 1 (text/plain, inline)]
Start emacs with emacs -Q and paste the following text in the scratch buffer

;;;; Start copy ;;;;
(defun test (nil)
  (test1
    (test2
    "") "***"))
;;;; End copy ;;;;

You will see that the last 7 characters of the last line, i.e., "***")) are
shown with the wrong face. If you insert a new line before those
characters, the correct face is shown.
