Have you thought of a minipage? For verbatim? Then there'll be some  
space on the left to fill with whatever. Maybe with \rule[lift]{width} 
{height}. As in:

	\rule{1mm}{1cm}
	\vspace*{1cm}\begin{minipage}[b]{0.96\linewidth}
	  \begin{verbatim}
	    (...)
	  \end{verbatim}
	\end{minipage}

The other way is not so easy to compute:

	\rule[-4mm]{1mm}{1cm}
	\begin{minipage}[t]{0.96\linewidth}
	  \begin{verbatim}
	    (...)
	  \end{verbatim}
	\end{minipage}
