I've read that, but I don't agree with the second paragraph. Universal
newline support is available only for input. This sentence is enough to
easily predict the behavior in every usage case, including "+" modes.
If there's any intent to add support to output, then I'd understand
the exclusion, since this would make backwards compatibility possible
(users of "rU+" could have their code broken, since they were doing
output by hand). Otherwise, it should be allowed, IMO.
