Thanks for contributing to Guix!

Please split this into three separate patches -- one each for librep,
rep-gtk and sawfish. For the commit messages, please use the
conventional Guix update commit message. If you use Emacs, this can be
done easily using the update yasnippet in etc/snippets of the Guix
source tree.

Shouldn't https://sawfish.tuxfamily.org/ be the home-page for all three
packages? Why are we listing the wiki as the home-page?

We don't usually package beta releases. So, there is no need to mention
this as a comment. But, the current release is 0.90.8.3. Please update
to that.
