The name is taken from CL's fresh-line but that doesn't mean it is best
suited. add-newline sounds like an alias to terpri, so it is the least
favourable. `ensure-newline' is acceptable to me. But if we choose
ensure-newline I'd like to add an alias to it in cl-lib.el.

Any suggestion on how to improve it?
