// The logic about the base branch and the tracking branch is as follows:
//
// * If a branch with the same name does not exist and no track is given, use the default
// branch
//
// * If a branch with the same name exists and no track is given, use that
//
// * If a branch with the same name does not exist and track is given, use the
// local branch that tracks that branch
//
// * If a branch with the same name exists and track is given, use the locally
// existing branch. If the locally existing branch is not the local branch to
// the remote tracking branch, issue a warning
