r116509 fixed the Win32 XFAIL.

The failing was due to this:
1. preamble.c contains CR+LF new lines
2. write() is called with a buffer containing the original (CR+LF) to output the result on the console.
3. In text mode(the default), write() convert LF to CR+LF even if LF is preceded by CR, hence we have CR+CR+LF which filecheck interprets as 2 lines.
