gnu: mercurial: Patch to make it read HGEXTENSIONPATH.
This will make Mercurial be able to find third-party extensions installed with Guix, without having to set PYTHONPATH. * gnu/packages/patches/mercurial-hg-extension-path.patch: New file. * gnu/local.mk (dist_patch_DATA): Register the patch. * gnu/packages/version-control.scm (mercurial)[origin](patches): Apply the patch. [native-search-paths]: Add HGEXTENSIONPATH. Signed-off-by: Ludovic Courtès <ludo@gnu.org>
