This is quite true, but if you're opening it in binary mode,
it's questionable whether there's anything that corresponds to
a "line" in the first place. This is, in fact, the standard distinction
between a 'text' and a 'binary' file: text files are organized into
lines, and binary files have some other organization, which is
strictly dependent on the kind of file.
