This seems like a much better solution than adding a whole static inner
class to java.lang.System.
Yet ... how much of a problem is this outside of the JDK itself and,
more generally, for new code rather than old?
If there are n (for n <= 43) problematic uses in the JDK then we could
just fix those without defining any new public API. For new code we
should encourage people to use String.format("...%n...") rather than
access the line.separator property explicitly.
