Красочные пред- и пост-обрывные токены с пакетом листингов

Question

Я хочу получить красочные prebreakи postbreakжетоны с listingsпакетом, но следующий код не работает:

\documentclass{article}
\usepackage{xcolor,listings}
\begin{document}
\begin{lstlisting}[basicstyle=\ttfamily,breaklines,prebreak={\space\color{teal}!},postbreak={\color{blue}!\space}]
This is a long line. This is a long line. This is a long line. This is a long line. This is a long line.
This is another long line. This is another long line. This is another long line. This is another long line.
\end{lstlisting}
\end{document}

Как можно решить эту проблему?
