Fixing and maintenance of emacs-guix (guix.el)

[John Soo]

Hi Guix,

emacs-guix (also known as guix.el) has been broken for some time.

I submitted https://gitlab.com/emacs-guix/emacs-guix/-/merge_requests/8
to support guix versions >= 1.1.  However, two changes also have to
occur for proper support.

* Some bindings will need to be exposed on the guix side. I submitted
  patches for this already: https://issues.guix.gnu.org/44619

* The guix package in gnu/packages/package-management.scm will need to
  refer to a commit including those patches.

That leads to a more nebulous question: should there be "stable" and
"unstable" versions of the guix package in guix?  Stable might be pinned
to a release, but guix-unstable might be updated occasionally.

What do you think?
