This is because the function stat_tracking_info() can not distinguish whether the upstream branch does not exist, or nothing is changed between one branch and its upstream. This patch changes the return value of function stat_tracking_info(). Only returns false when there is no tracking branch or the tracking branch is invalid, otherwise true. If the caller does not like to report tracking info when nothing changed between the branch and its upstream, simply checks if num_theirs and num_ours are both 0.
