To those versions of Mac OS that use \r as the native line end.  Part of
text-mode writing is converting \n to \r then (and part of text-mode reading
is converting \r to \n; if you don't have any ord('\n') bytes in your binary
data when writing in text mode on such a Mac, then it won't make any
difference; if you do have any ord('\n') bytes in your binary data when
writing in text mode on such a Mac, then all such bytes will be corrupted in
the output).
