Note that Python does nothing special in the above case. For non-Windows
platforms, you'd get two different results -- the conversion from \r\n to
\n is done by the Windows C runtime since the default open() mode is text mode.

Only with mode 'U' does Python use its own universal newline mode.

With Python 3.0, the C library is not used and Python uses universal newline
mode by default.

Four shall be the number of spaces thou shalt indent, and the number of thy
indenting shall be four. Eight shalt thou not indent, nor either indent thou
two, excepting that thou then proceed to four. Tabs are right out.
