[AUCTeX] A problem with \parencite and fill-paragraph

[aufc]

Hello everybody,

In auctex-mode, given

--8<---------------cut here---------------start------------->8---
asdf asdf asdf asdf asdf asdf asdf asdf asdf asdf asdf asdf xxxx 
\parencite{asdf}
--8<---------------cut here---------------end--------------->8---

after calling `fill-paragraph` I get the following

--8<---------------cut here---------------start------------->8---
asdf asdf asdf asdf asdf asdf asdf asdf asdf asdf asdf asdf
xxxx \parencite{asdf}
--8<---------------cut here---------------end--------------->8---

(note that xxxx gets wrapped to the new line even though it should stay
in the same line)


Here's the result when I use \cite instead of \parencite:

--8<---------------cut here---------------start------------->8---
asdf asdf asdf asdf asdf asdf asdf asdf asdf asdf asdf asdf xxxx
\cite{asdf}
--8<---------------cut here---------------end--------------->8---

I guess it has something to do with the initial letters of \parencite
which are the same as \par and \par is treated in a special way by
fill-paragraph.


Is there any solution (or workaround) to this problem?

Thanks for help in advance!

Cheers,
Adam
