Before 3.0 at least, if you copy a text file from, say, Windows to Mac, and
open it with 'r', you get lines which end in '\r\n'. Here's a simple
example:
>>> open("dos.txt", "rb").read()
'a single line\r\nanother line\r\n'
>>> f = open("dos.txt")
>>> f.next()
'a single line\r\n'
>>> f = open("dos.txt", "r")
>>> f.next()
'a single line\r\n'
>>> f.next()
'another line\r\n'
If, on the other hand, you open it with 'rU', the '\r\n' literal line ending
is converted, even though CRLF is not the canonical Mac line ending:
>>> f = open("dos.txt", "rU")
>>> f.next()
'a single line\n'
>>> f.next()
'another line\n'
