# How to convince fancyvrb to give overfull warnings?

The following document

\documentclass{article}
\usepackage{fancyvrb}
\begin{document}
\hsize=1cm
\begin{Verbatim}
foo bar foo bar foo bar foo bar foo bar
\end{Verbatim}
\end{document}


does not give a warning. But I do want to see when something is bigger than it is supposed to be. What can I do?

(The Verbatim environment is produced by pygmentize, so I'd prefer a solution that does not involve changing it.)

-

\RecustomVerbatimEnvironment{Verbatim}{BVerbatim}{}

at least during testing. However, some options for Verbatim do not apply to BVerbatim.
