docstr: D205: Put one blank line between summary line and description.
  
  Multi-line docstrings consist of a summary line just like a one-line
  docstring, followed by a blank line, followed by a more elaborate
  description. The summary line may be used by automatic indexing tools;
  it is important that it fits on one line and is separated from the
  rest of the docstring by a blank line.
