It didn't seem to help.

Here is a screencast which shows me evaluating the new code with 
eval-buffer (somewhere in the middle of the video), and still seeing the 
prompt when I repeat a certain sequence of actions:

- Show the diff buffer (for window.el), actually.
- Quit it with 'q'.

BTW, despite me answering the prompt 'n' the width gets adjusted anyway.

Hope the link works, if not, I can reupload it somewhere else:
