The following code...
import sys
if sys.platform == "win32":
import os, msvcrt
msvcrt.setmode(sys.stdout.fileno(), os.O_BINARY)
sys.stdout.write("This is a sample line of text\n")
...results in the stdio output ending with 0x0d followed by 0x0a. stdio is set to binary mode. Why is the write() call still substituting \r\n for \n?
