Once you made a commit, and you are statisfied with it, then you can run:
git format-patch -1
to create a patch form the last commit.
I would store it somewhere outside the repository, so that it does not
get in your way later as an utracked file.
You can also specify the output directory directly with -o.

Once this is done, a patch file is created, with a name resembling the
commit message.
You can then do:
git send-email <patch-filename>

It will ask for the e-mail address you want to send to, you should
specify the guix-patches mailinglist.

Hope that helps.
