Ever since the dawn of time, line termination is "\n" in C and C++.

The file streams and devices translate the \n to the appropriate line 
termination sequence on the platform. That's LF on Unix (matching the '\n'), 
CRLF on DOS and Windows, CR only on Mac OS 9.

So you should always use \n and open your file streams in text mode (the "t" 
option to fopen or QIODevice::Text to QIODevice::open).

If you're writing an application that deals with text files from other 
platforms, treat all files as binary and detect the three possibilities.
