They absolutely do not add linends to the date. The supplied data gets
converted into a string and is appended to the array with no additional
processing. If there are extra linends, it's because you left them on the
line before making the call. WriteError() and WriteOutput() assume you have
done any linend processing yourself, WriteXXXBuffered() assumes you are
writing a buffer of data with individual lines separated by linends and the
separation is handled for you.
