/// <remarks>
/// Parse the tag message and return the first "line" of it.
/// <p>
/// The first line is everything up to the first pair of LFs. This is the
/// "oneline" format, suitable for output in a single line display.
/// <p>
/// This method parses and returns the message portion of the tag buffer,
/// after taking the tag's character set into account and decoding the buffer
/// using that character set. This method is a fairly expensive operation and
/// produces a new string on each invocation.
/// </remarks>
/// <returns>
/// decoded tag message as a string. Never null. The returned string
/// does not contain any LFs, even if the first paragraph spanned
/// multiple lines. Embedded LFs are converted to spaces.
/// </returns>
