Subject: 29.1; Comment or uncomment lines in elisp-mode will show message in
 minibuffer

Hello Emacs,

When update to the new released Emacs 29.1, I found that when comment or
uncomment lines in emacs-lisp-mode will show message in minibuffer as
below:
```
combine-change-calls: buffer-undo-list broken
```
Steps to reproduce:
1. create a test.el file with any Elisp code. such as:
```
(message "Test")
```
2. start emacs and open the test.el file with `emacs -Q ~/test.el`
3. Use C-x C-; (comment-line) to comment the code in test.el
4. Now you will see the message mentioned above.

This issue also happened on Emacs 29.1 on Windows OS.

----
Best regard, Eason Huang
