I do not see how the comment relates at all to the code following it -
buffer mode and line end mode are two different things. Also, the
repeated calls to strlen(line) are horribly inefficient - it should be
called once and stashed in an int (I once made an order of magnitude
speedup in a program by correcting a piece of someone else's code that
looked like this: for (i = 0; i <= strlen(s); i++) where s was an
invariant very long string)
