Oh, no wonder that this looked familiar. It solves the same issue
as 48b8d3cf ("usage_with_options: omit double new line on empty
option list", 2017-08-25) and of course it conflicts with it.
I find the solution presented with this patch is more direct and
straightforward, leaving less chance to future breakage. Besides
it comes with tests ;-), so perhaps I should drop the other one.
