Ok, actually it boils down to the following code in Modules/main.c:
if (Py_UnbufferedStdioFlag) {
#if defined(MS_WINDOWS) || defined(__CYGWIN__)
_setmode(fileno(stdin), O_BINARY);
_setmode(fileno(stdout), O_BINARY);
#endif
... which explains things quite clearly! Archeology leads to r7409 by Guido in 1997:
