[Bug-AUCTeX] RefTeX cannot manage multiple "bibliography" macros

[Mosè Giordano]

Hi all,

it seems RefTeX (I'm running Emacs 24.3.1) cannot manage multiple
bibliography database files specified using multiple `\bibliography'
macros.  Consider these examples:

  \bibliography{foo,bar}

and

  \bibliography{foo}
  \bibliography{bar}

(`foo' and `bar' must be two existent database files).  In the first
case `reftex-get-bibfile-list' returns something like

  ("/tmp/foo.bib" "/tmp/bar.bib")

while in the second only

  ("/tmp/foo.bib")

I'm not familiar with RefTeX code, can someone please look at this
problem?  It's a RefTeX-only problem, AUCTeX without RefTeX works as
expected in both cases.

Thank you,
bye,
Mosè
