commit 09b634565d6102a2d87302bcf83a290fb6fe862a

    emacs: Move the code to load Emacs packages after installing.
    
    This code should belong to "guix-backend" as it is run after a REPL
    operation to check if new Emacs packages have been installed and to
    autoload them if needed.
    
    * emacs/guix-emacs.el (guix-emacs-activate-after-operation)
    (guix-emacs-load-autoloads-maybe): Move and rename to...
    * emacs/guix-backend.el (guix-emacs-activate-after-operation)
    (guix-repl-autoload-emacs-packages-maybe): ... this.
    (guix-after-repl-operation-hook): Adjust for the renaming.
