To me there are basically two reasons that make newl desirable beside the
formatting issue.

1. std::endl was and is still abused heavily. I think there is a reason for
this. Most c++ programmers are taught to stay clear of ugly low-level c
things and to use the new shiny c++ facilities instead. And that's what they
do, replace '\n' with std::endl. Personally I believe this reason alone
justifies a std library extension std::newl.

2. IIUC the difference between a character and a manipulator is that the
manipulator is not tied to the streams character type. So for some
applications '\n' does not suffice. To me stream.widen('\n') is sufficiently
ugly to justify a newl modifier.
