> LF is line feed, thus new line.

  LF is line feed, thus next line.
                                   The CR
                                          is to
  readjust the write head
  back to the
  starting position.

A line feed alone is not a new line because some or most of the line is already used up. The B '*n' and C '\n' introduced the notion of new line, which outputs both a next line (LF) and back to the starting position (CR).
