case where 'packages-by-name' returns the empty list.
Co-authored-by: Mathieu Lirzin <mthl@gnu.org>
This is a followup to commit 1b846da8c3.

of "-".

* emacs/guix-emacs.el (guix-emacs-autoload-packages): Autoload Emacs
packages installed in a system profile.
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...

'load-path' and finally, load autoloads.
* doc/emacs.texi (Emacs Initial Setup): Adjust accordingly.
Reported by Christopher Allan Webber <cwebber@dustycloud.org> on #guix.
Several modules use the code from 'guix-profiles' without requiring it. It
was never noticed before commits e4e2154644
and 13fe4891fa, because 'guix-emacs' required
this module. But now, when 'site-start.el' loads 'guix-emacs',
'guix-profiles' may not exist yet, so it may not be required. This will
lead to an error when some of "M-x guix-..." commands will be used. See
<https://gnunet.org/bot/log/guix/2016-02-03#T898859>.

'profile-diff'.
(guix-message-outputs-by-diff): Adjust accordingly.
For a usual profile, packages are placed in a profile directory itself,
but for a system profile, packages are placed in 'profile'
sub-directory. So we need to do some special cases for system profiles
to find packages there as well.

This fixes a regression introduced in commit 7171d824.
'insert-text-button' procedure does not allow to override a button face,

(guix-package-info-insert-heading): Use it.
"guix-emacs.el" may be used just for "instructing" Emacs where to find
Emacs packages installed with Guix, so it should have as few
dependencies as possible.
See <http://lists.gnu.org/archive/html/guix-devel/2016-01/msg00022.html>.
