\noindent and list environments: class="ltx_noindent" in wrong <para> in some cases

[siegfriedzoetzsche]

Sometimes, the \noindent information seems to get lost in \items such as

\item A\par\noindent a

This seems to depend on whether such an \item is followed by a blank line or not.
I have seen this behaviour with {trivlist}, {itemize} and {enumerate}.

Examples:
No blank lines after \item (two class="ltx_noindent" missing one in the wrong <para>) :

\documentclass{article}
\begin{document}
\begin{trivlist}
\item A\par\noindent a
\item B\par b
\item C\par\noindent c
\end{trivlist}
\end{document}

Converted to:

[...]
<para xml:id="p1">
  <itemize>
    <item>
      <tags>
        <tag/>
      </tags>
      <para xml:id="p1.p1">
        <p>A</p>
      </para>
      <para xml:id="p1.p2">
        <p>a</p>

        <p>B</p>
      </para>
      <para xml:id="p1.p4">
        <p>b</p>
      </para>
    </item>
    <item>
      <tags>
        <tag/>
      </tags>
      <para xml:id="p1.p5">
        <p>C</p>
      </para>
      <para xml:id="p1.p6">
        <p>c</p>
      </para>
    </item>
  </itemize>
</para>

Blank lines between \items but not before \end{trivlist} (one class="ltx_noindent" missing one in the correct <para>) :

\documentclass{article}
\begin{document}
\begin{trivlist}
\item D\par\noindent d

\item E\par e

\item F\par\noindent f
\end{trivlist}
\end{document}

Blank lines after every \item (looks good):

\documentclass{article}
\begin{document}
\begin{trivlist}
\item G\par\noindent g

\item H\par h

\item I\par\noindent i

\end{trivlist}
\end{document}

Ah, indeed, there's a bunch of implied \par in there. I think I've got it right, now. Thanks for the report.
