Note that I think (and Johannes--cc'd--could confirm) that what you want
is '--left-only' to discard rebased changes from the upstream branch:
Does that mean range-diff got --left-only and --right-only
backwards? IOW, doesn't
$ git log --left-only A...B
show what is shown in "git log B..A", and if so, shouldn't
$ git range-diff --left-only A...B
which is a synonym for
$ git range-diff B..A A..B
also give commits in the B..A range?
Puzzled....
