I will split the patch into two. The 1st patch resolves a real problem:
branch: not report invalid tracking branch
Command "git branch -vv" will report tracking branches, but invalid
tracking branches are also reported. 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.
And in the 2nd patch, I will not mention "git push" (current not be
pushed out ...) any more, and only focus on "git status". It's just
a suggestion, may only fit small group of users' taste.
