This enables the use of the subdirs.el feature of Emacs, where specifying a directory in EMACSLOADPATH translates into a `load-path' variable containing the directory and all its sub-directories. * gnu/packages/aux-files/emacs/guix-emacs.el (guix-emacs-autoload-packages): Use `load-path' directly instead of parsing EMACSLOADPATH.
