Probably not too much, and we would skip buffering for JSON as we don't
need to print columns, so we don't have to care about buffering and
rendering performance too much.

All it takes is to extend a bit the out() function and pass the right
arguments to it -- it looks way easier than implementing format
strings, even though I'd like the latter more.
