xelatex produces off-by-one error in listings package

[Bob Plantz]

The following LaTeX code produces good PDF with pdflatex, but the \lstinline adds one to each character (e.g., "abc" -> "bcd") with the \listingsfont from the listings package.

\documentclass{article}
\usepackage{bera}
\usepackage{listings}
\usepackage{ifxetex}
\ifxetex
   \usepackage{fontspec}\newfontface\listingsfont[Path]{fvmr8a.pfb}
   \newfontface\listingsboldfont[Path]{fvmb8a.pfb}
\else
   \edef\oldtt{\ttdefault}\usepackage[scaled]{beramono}\usepackage[T1]{fontenc}
   \renewcommand*\ttdefault{\oldtt}\newcommand{\listingsfont}{\fontfamily{fvm}\selectfont}
   \renewcommand*\ttdefault{\oldtt}\newcommand{\listingsboldfont}{\fontfamily{fvm}\selectfont}
\fi
\lstset{basicstyle=\listingsfont}
\begin{document}
An example that uses the listingfont to render ``int hms 0123'': \lstinline?int hms 0123?

Now for a program not using the listingfont:
\begin{lstlisting}[language=C]
#include <stdio.h>

int main(void)
{
    printf("Hello world.\n");
    return 0;
}
\end{lstlisting}
\end{document}
