This patchset fixes a couple of issues discovered in bug #22550 (see the
bottom of <http://debbugs.gnu.org/cgi/bugreport.cgi?msg=14;bug=22550>).
[PATCH 1/4] emacs: Factorize searching for Emacs packages.
[PATCH 2/4] emacs: Find Emacs packages in a system profile.
[PATCH 3/4] system: Fix EMACSLOADPATH.
This is an easy fix, however I've just thought that we can get rid of
EMACSLOADPATH completely. Since now our Emacs can load packages from
guix directories ("~/.guix-profile" and "/run/current-system/profile")
there is no need to use "/etc/emacs/site-start.el" anymore, because Emacs
will load "guix-autoloads.el" and "geiser-autoloads.el" from a system
profile.
So I think this patch is OK as a current fix, but eventually we should
remove "guix-init.el" and "/etc/emacs/site-start.el". I'll send a
patch for it later.
[PATCH 4/4] doc: Document 'guix-edit' Emacs command.
