I wouldn't get rid of `--show-name`, as it also implicitly brings along
`--no-show-name`, basically checking the box for (3).

In any case, I agree that it probably makes sense to do (2). Unless I'm
mistaken, the only case we need to care about is `--regexp`, because
without all the emitted names would be the same anyway.
