Subject: [PATCH] config: Accept empty branch in SCM dict
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

If user sets `branch` to `None`, it should behave as if the branch is
not set at all. Nagging them about removing it is not helping anything.

Fixes: #415
