Oh, I see.
\includegraphics[draft]{filename} prints the filename instead of the
figure, so there is obviously a way to print arbitrary characters in a
verbatim way, without using verbatim.
This works, it's based on \includegraphics[draft] from
graphics/graphics.sty:
<preamble>
\def\stripprefix#1>{}
\newcommand*{\xfiginput}[1]{%
\edef\tempfilename{#1}%
\InputIfFileExists{#1}{}{%
\fbox{Could not find file
\ttfamily\expandafter\stripprefix\meaning\tempfilename
!}}}
</preamble>
That was fun.
