listings bug: space after literate replacement lost with spaceflexible/fullflexible columns

Question

Problem with space being lost in listings immediately after a literate replacement when using columns=spaceflexible or columns=fullflexible (appears correctly with columns=flexible). A small example follows, with problem being that the space after the replaced operator is lost.

Note: This problem is extremely similar to one posted earlier today, but this time, the problem involves the space after a literate replacement, and the space is lost in both \lstinline and lstlisting modes (previous question involved string replacement, and error occurring only in \lstinline mode).

enter image description here

\documentclass{article}
\usepackage{listings}
\lstset{literate=*{{+}{*}{1}}, columns=fullflexible}

\begin{document}

\noindent
\begin{tabular}{ll}
flexible & \lstinline[columns=flexible]!1 + 1!\\
spaceflexible & \lstinline[columns=spaceflexible]!1 + 1!\\
fullflexible & \lstinline!1 + 1!\\
\end{tabular}

\bigskip
\noindent
Within lstlisting environment with columns=flexible
\begin{lstlisting}[columns=flexible]
1 + 1
\end{lstlisting}

\noindent
Within lstlisting environment with columns=spaceflexible
\begin{lstlisting}[columns=spaceflexible]
1 + 1
\end{lstlisting}

\noindent
Within lstlisting environment with columns=fullflexible
\begin{lstlisting}
1 + 1
\end{lstlisting}

\end{document}

You can use the option keepspaces. For more details have a look at the documentation.

enter image description here

\documentclass{article}
\usepackage{listings}
\lstset{literate=*{+}{*}{1}, columns=fullflexible,keepspaces}

\begin{document}

\noindent
\begin{tabular}{ll}
flexible & \lstinline[columns=flexible]!1 + 1!\\
spaceflexible & \lstinline[columns=spaceflexible]!1 + 1!\\
fullflexible & \lstinline!1 + 1!\\
\end{tabular}

\bigskip
\noindent
Within lstlisting environment with columns=flexible
\begin{lstlisting}[columns=flexible]
1 + 1
\end{lstlisting}

\noindent
Within lstlisting environment with columns=spaceflexible
\begin{lstlisting}[columns=spaceflexible]
1 + 1
\end{lstlisting}

\noindent
Within lstlisting environment with columns=fullflexible
\begin{lstlisting}
1 + 1
\end{lstlisting}

\end{document}
