What exactly do you mean with `validate with empty line`? You mean that simply pressing `<enter>` after the first page will advance to the next page?

That somehow changes the semantics of an "empty command". I'm not sure that's a good thing. But the only alternative that comes to my mind would be to paginate the results, meaning that after showing the results the prompt doesn't return to the menu but shows options to continue to the next page or to quit the pagination, similar to the way `less` does it.

But that's not great either, because the 90% use case is probably to simply use the first page and not to use the pagination.

Any ideas? @quigybo, @octogene?
