nmbug-status: Use 'show-ref --heads' for loading configs

When loading configs from Git, the bare branch name (without a
refs/heads/ prefix or similar) matches all branches of that name
(including remote-tracking branches):

  .nmbug $ git show-ref config
  48f3bbf1d1492e5f3d2f01de6ea79a30d3840f20 refs/heads/config
  48f3bbf1d1492e5f3d2f01de6ea79a30d3840f20 refs/remotes/origin/config
  4b6dbd9ffd152e7476f5101eff26747f34497cee refs/remotes/wking/config

Instead of relying on the ordering of the matching references, use
--heads to ensure we only match local branches.

+nmbug-status
+------------
+
+`nmbug-status` now only matches local branches when reading
+`status-config.json` from the `config` branch of the `NMBGIT`
+repository.  To help new users running `nmbug-status`, `nmbug clone`
+now creates a local `config` branch tracking `origin/config`.  Folks
+who use `nmbug-status` with an in-Git config (i.e. you don't use the
+`--config` option) who already have `NMBGIT` set up are encouraged to
+run:
+
+    git checkout config origin/config
+
+in their `NMBGIT` repository (usually `~/.nmbug`).
