I actually had another question that I answered myself: how do I know
which one to choose? There's no preview option (and I'm lazy, I don't
want to do separate diff commands myself). So my answer was "choose
both, then delete the one that does not look good (and explain it in
the cover too when I delete it)"

Yes of course. We can revisit this later.
