By assuming that if it's the last character in the string, it came from a mac file and
is the line terminator. Similarly for '\r\n' (dos) and '\n' (unix) when at the end of
the string.
It might be cute to have a MacTextFile class etc. that ensures that the line endings
are consistent, but personally I think that is overkill (and is likely to be very
slow).
