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,
