[AUCTeX-devel] 27.0.50; Wrong parsing of key-val labels

[Arash Esbati]

Hi all,

Please consider the following LaTeX code in a buffer where RefTeX is
enabled:

--8<---------------cut here---------------start------------->8---
\documentclass{article}
\usepackage{listings}
\begin{document}

\begin{lstlisting}[
caption = Some caption ,
label   = lst:1        %
]
foo
\end{lstlisting}

\begin{lstlisting}[
caption = {[Short caption]Long caption},
label   = lst:2          
]
bar
\end{lstlisting}

\begin{lstlisting}[
language  = {[LaTeX]TeX}                           ,
frame     = single                                 ,
caption   = {[Short caption]\textit{L\textbf{o}ng} caption} ,
label     = lst:3     ]
foobar
\end{lstlisting}

\end{document}
--8<---------------cut here---------------end--------------->8---

When hitting `C-u C-c )' in order to add a \ref, RefTeX fails to see the
last 2 labels.  For the first one, it inserts

\ref{lst:1        %
}

The is due to the second regexp in `reftex-label-regexps'.  Please find
attached a patch fixing this issue.  Any comments welcome.

Best, Arash
