[l2h] Controlling TOC

[Graham Gough]

When processing the following dcoument using l2h 99.1, I cannot stop
the subsections appearing in the TOC

\documentclass{article}
\title{Toctest}
\begin{document}
\maketitle
\section{One}
\subsection{One a}
\subsection{One b}

\section{Two}
\subsection{Two a}
\subsection{Two b}
\end{document}

I always get a front page with

      One 
            One a 
            One b 
      Two 
            Two a 
            Two b 
      About this document ... 

whatever value of $TOC_DEPTH, or arg to -toc_depth I use
I've also tried using subsection* and I have the same problem

Is this a known problem, or am I just doing something stupid?
