Perhaps not exactly what you asked for, but the fancyvrb package  
might have things to help you get what you want. Looking at its  
manual using "texdoc fancyvrb", the following comes perhaps close to  
what you want:

\usepackage{fancyvrb}
\begin{document}
    \begin{Verbatim}[frame=leftline]
   (...)
   more stuff here
   and more
   \end{Verbatim}
\end{document}
