That's a good question. I think it should. That `println` method is not specified in terms of `printf` or `format`. Thus, we cannot reduce `println` to, say, `printf("%s%n", obj)`, leaning on `Formatter`'s definition of `%n`:

    'n'	line separator	The result is the platform-specific line separator

@stuart-marks, any thoughts on wording? Mind you, if we add any such wording, we'll have to update CSR too.
