log --cherry: a synonym

At the porcelain level, because by definition there are many more contributors
than integrators, it makes sense to give a handy short-hand for --right-only
used with --cherry-mark and --no-merges.  Make it so.

In other words, this provides "git cherry with rev-list interface".
