Subject: gnu: Search for patches under $GUIX_PACKAGE_PATH.
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Fixes <http://bugs.gnu.org/19364>.
Reported by Tomáš Čech <sleep_walker@suse.cz>
and Mark H Weaver <mhw@netris.org>.

* gnu/packages.scm (%patch-path): Move after definition of
  %package-module-path'.  Append "/gnu/packages/patches" only to
  %DISTRO-ROOT-DIRECTORY.
* tests/guix-package.sh: Add 'emacs-foo-bar-patched' test.
