It's not a bug.

On Windows, "\n" evaluates to a carriage return and a line feed, what
you may be used to calling "\r\n". If you open blaat.txt in SciTE (or
any similar text editor) and view the ends of lines (View -> End of
Line), you'll see.

So what's happening is that f.write "test\r\n" is writing a carriage
return, then "\n" which is a carriage return and a line feed.
