[AUCTeX] Supporting biblatex's \addbibresource

[Rasmus Villemoes]

I recently switched to biblatex/biber, and with the help of some of
the postings on this list as well as the biber manual, I almost got
everything to work as it used to. The one thing that didn't work was
that reftex doesn't seem to recognize \addbibresource (or any of its
friends from biblatex), so I got the error "No valid bibliography
[...]". For now, my fix is to write

\addbibresource{rv-utf8.bib}
\iffalse
\bibliography{rv-utf8}
\fi

in my preamble. Of course, I could also stick to the legacy
\bibliography command, but since its deprecated, I prefer to use
biblatex's native methods. Is there a way (for the end user) to tell
reftex that \addbibresource should be treated as \bibliography? Or can
this be integrated in some future version of auctex/reftex?

Thanks,
Rasmus
