Although directives such as "note" and "warning" will accept content
immediately following the directive, this is technically where arguments to the
directive should go (see http://sphinx.pocoo.org/rest.html#directives). Putting
the content there means that any lines beginning with an inline text role
(e.g. ":setting:`DEBUG`") will be mis-interpreted as an option block for the
directive. To avoid this error, there should always be a blank line between the
directive start and the directive content.
