lilyp pushed a commit to branch emacs-team
in repository guix.

commit a3ac317ab4a90f66ac65055fa26dee58ed2367b8
Author: Liliana Marie Prikler <liliana.prikler@gmail.com>
AuthorDate: Fri Jun 9 13:28:44 2023 +0200

    gnu: Construct Emacs packages from bottom up.
    
    This makes relationships within the Emacs variants slightly easier to reason
    about.  In particular, it makes it so that inputs get added on top of the
    previous stack rather than removed (which brings the risk of not adjusting
    changes downwards).
    
    * gnu/packages/emacs.scm (emacs-minimal): Expand package definition.
    [inputs]: Reorder and add bash-minimal.
    (emacs-no-x): Inherit from emacs-minimal.
    (emacs): Inherit from emacs-no-x.
    (emacs-motif, emacs-no-x-toolkit): Inherit from emacs-no-x.
    Only inherit inputs from emacs.

-documentation on all aspects of the system, from basic editing to writing
-large Lisp programs.  It has full Unicode support for nearly all human
