Notes in captions longer then one line are duplicated

[Canageek]

As it says, if your caption is longer then one line, you get two captions in the bibliography. UNLESS you use \bibnote[test]

Example provided.

\documentclass{article}

\usepackage{notes2bib}
\bibnotesetup{cite-function=\autocite}

\usepackage{biblatex}

\begin{document}


\begin{figure}[h]
	\caption{Left is printed in the ellipsoidal style, middle is printed as a ball\bibnote{I am printed once.}	}
\end{figure}

\begin{figure}[h]
		\caption{Left is printed in the ellipsoidal style, middle is printed as a ball and stick figure, and right is printed as a spacefilling model.\bibnote{I am printed twice.}	}
\end{figure}

\begin{figure}[h]
	\caption{Left is printed in the ellipsoidal style, middle is printed as a ball and stick figure, and right is printed as a spacefilling model.\bibnote[test]{Oddly, I am printed only once.}	}
\end{figure}

\printbibliography
\end{document}

OK, the issue arises as with the longer caption the text is typeset twice, and that triggers an increment of the global counter used to track note number. It doesn't happen with the last entry as that doesn't use the counter (but it does write the data twice).

I guess in terms of a fix, what I can do is save the literal text of the note. If that's already been seen/written, we don't write it again but rather refer back to it. That would mean that someone repeating say See XXX might get a change of output, but that's likely to be what they want anyway.

I might need a little while on this one: I likely need first to update the general structure of notes2bib to follow most recent LaTeX3 ideas.
