Just checked it in.

Another reason to use \r\n over \n is that it'll only cause issues for
Unix people who tend to be familiar with handling such issues.  In other
words, every Unix user knows how to remove ^M's, but not every Windows
user know what to do when Notepad shows one long line.  :-)

Are we sure that passing System.out to XMLOutputter on Unix will always
look right though?
