Hey Junio,
I just saw this message when switching branches:
-- snip -- Switched to branch "fiji" Your branch is behind the tracked remote branch 'origin/fiji' by 9 commits, and can be fast-forwarded. -- snap --
It really helped a lot (I would have tested the old version, and would not have been able to reproduce the bug I have been told about).
So this really saved me some frustrating hours.
Thanks, Dscho
