I agree with the patch, but I would use a different reasoning. Your
example here is not even correct because the range in the second command
would be empty unless the merge conflicted.
I believe the more common confusion stems from the tracking displays in
git-checkout and others. The issue there is that we *internally* treat
origin/masters as a kind of mirror, and the tracking displays all go
against user expectations once they have seen a newer state of origin's
master by explicit pull or fetch.
Michael also pointed out yesterday that short of
git fetch origin master:refs/remotes/origin/master
there is no way to fetch only one branch.
