  git_branch_set_upstream with local branches Currently git_branch_set_upstream when passed a local branch creates invalid configuration, for ex. if we setup branch 'tracking_master' to track local 'master' libgit2 generates the following config ``` [branch "track_master"] remote = . merge = .refs/heads/track_master ``` The merge value is invalid and calling git_branch_upstream on 'tracking_master' results in invalid reference error. It should do: ``` [branch "track_master"] remote = . merge = refs/heads/master ```
