Subject: [PATCH 2/3] gnu: emacs: Remove custom guix-emacs code.
This used to be necessary to find the Elisp library modules, but is no longer
the case. The environment variable EMACSLOADPATH/search path specification is
now used for that purpose.
* gnu/packages/aux-files/emacs/guix-emacs.el: Remove file.
* Makefile.am (AUX_FILES): Unregister it.
* gnu/packages/emacs.scm (emacs)[phases]: Remove the 'install-site-start
phase.
[native-inputs]: Remove the "guix-emacs.el" input.
