I just happened to come upon a use case where the `A..B` way is not actually useless: just after fetching a branch, I got the usual update lines, and it is pretty convenient to be able to use them not only for `git log`, but also for `git diff` invocations, to see what actually changed (from two angles). So maybe you could register this as a vote to not totally strike the A..B notation from the manual. Ciao, Dscho
