And a bit more, isn't it?
The --keep-redundant-commits option implies the --allow-empty option
and it was perfectly acceptable to give both. By making sure that
only at most one of -k-r-d, -a-e or -s-e is given, this forbids that
usage.
"It is implied so there is no *need* to give it redundantly" is
different from "It is implied so you shouldn't give it redundantly".
Like 7 and 8 that adds --quiet/--skip, don't we want this also for
revert?
