Appending to a single line docstring places the message on a new line,
with a blank line separating it from the rest of the docstring.
The docstring ends with a newline, conforming to Twisted and PEP 8
standards. Unfortunately, the indentation is incorrect, since the
existing docstring doesn't have enough info to help us indent
properly.
