git-status: show the remote tracking statistics

gitster · gitster · commit b6975ab59b07 · 2008-07-02T23:32:25.000-07:00
This teaches "git status" to show the same remote tracking statistics
"git checkout" gives at the beginning of the output.

Now the necessary low-level machinery is properly factored out, we can do
this quite cleanly.
