LaTeX sets \textwidth =3D=3D \hsize at startup, then = makes \linewidth
track the current width in nested indented = environments, or in
multiple column printing.

The correct approach to your example is to box things = up to \linewidth
instead of \textwidth. Here is an example from = an upcoming TUGboat
article, where I wanted to frame figures (which = themselves contained
verbatim text):

% figbox draws a box around its contents, which
% can even contain verbatim text!
\newbox\thefigbox
\newenvironment{figbox}{%
    = \setbox\thefigbox\hbox\bgroup
    \advance\linewidth by -2\fboxsep = %make outer box dimension =3D=3D linewidth
    \advance\linewidth by = -2\fboxrule
    \hss
    = \begin{minipage}{\linewidth}%
}{%
    \end{minipage}%
    \hss
    \egroup
    \fbox{\box\thefigbox}
}

Here is an example of its use:

\begin{figure}[p]
\begin{figbox}
\begin{small}
\begin{verbatim}
LaTeX Mode: Major editing mode for LaTeX and
SLiTeX, with tex-mode underneath.
..
\end{small}
\end{figbox}
\caption{Online summary of \LaTeX{} = mode.}
\end{figure}
