There is _no_ correct way of splitting a file containing binary data in
lines because binary data may contain newline bytes that do not indicate a
new line. E. g.

>>> struct.unpack("l", "\r\n\r\n")
(168626701,)

how should Python know whether it just encountered two empty lines or the
integer 168626701?
