Nitpick: not documented in info '(standards) Style of Change Logs', but
I think you don't need to put commas after the file names above.  It
should rather look like below, I think:

--8<---------------cut here---------------start------------->8---
* file_one
* file_two
* file_three: Rewrite in terms of ...
--8<---------------cut here---------------end--------------->8---

I'd drop 'GUIX: ' at the front of the above comment.
