Explain that paragraph only containing one command may not have ps

[tlienart]

E.g.

\newcommand{\foo}{abc}

ABC

\foo

DEF

will give

<p>ABC</p>

abc

<p>DEF</p>

because Franklin doesn't know whether \foo inserts text or not and so, by default, considers it might be a no-paragraph case (e.g. \toc).

Can use the command \par in the definition so

s = raw"""
       \newcommand{\foo}{\par{abc}}

       ABC

       \foo

       DEF
       """

will lead to

<p>ABC</p>
<p>abc</p>
<p>DEF</p>
