Just a question.
I think, I have Linux 4.15.11 (from Debian testing) now. And there are no such files.
Are there any estimates about when this feature is expected to be available?

Will have undesired effects with NDEBUG.

Same here.

If you move this into the loop itself, the tool will adapt to changes in
terminal width and height dynamically.
