 When encoding data, new lines can optionally be inserted to wrap data. Encoding
 should normally emit the Unix new line character of `\n` when wrapping, but
 could emit '\r\n' if desired.  Decoding data ignores all new lines, including
-windows new lines.   So decoding should ignore `\n` and `\r\n`.
