Subject: [PATCH] import: elpa: Don't hardcode default branch to 'master'.
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Otherwise, remotes without a branch named 'master' will cause an error when
importing.

* guix/import/elpa (git-repository->origin): Fallback to HEAD instead of the
  'master' branch.
