Where is it documented that sys.stdin uses universal newlines mode? The newline behavior isn't documented in the sys module [1], though it should be. It's hard coded in create_stdio() in Python/pylifecycle.c [2]. In Windows it uses universal-translated mode. On all other platforms, it uses "\n", which includes "\r\n" but not "\r".
