Message buffer used for formatting streaming lines. The buffer is public
so that, if more complex formatting is needed than is provided by the
displayStreamingLine() methods, then it can be used externally to format
any required messages. The version of displayStreamingLine() with no
arguments can then be called to print the contents of the buffer.
