Parse repo.namespace

This contains the unexpanded name of the namespace
rather than the base ref of the namespace,
since the git namespace mechanism works by setting GIT_NAMESPACE
and on the first call to get_git_namespace() it gets expanded.

We need to save this for a later call to prepare_repo_cmd,
rather than trying to process it here,
since we can only do it once,
and we have other uses for the unexpanded name.
