title: QString::split() and "\r", "\n" and "\r\n" convention
body: <p>I understand that <code>QString::split</code> should be used to get a <code>QStringList</code> from a multiline <code>QString</code>. But if I have a file and I don't know if it comes from Mac, Windows or Unix, I'm not sure if <code>QString.split("\n")</code> would work well in all the cases. What is the best way to handle this situation?</p>
