[Bug-AUCTeX] Problems with Font-latex-user-keyword-classes

[Martin Sjöstrand]

I'm having serious problems with highlighting the keyword \footcite and
is hoping that someone can help me.

First of all, I have read the description but still can't get it to
work. 
I have specified the name: footcite
the keyword:footcite (omitting the \)
then I have set the face attribute: Foreground: green
and value: Command with arguments.

Now, only \footcite gets highlighted, but in red. How do I highlight the
arguments? I have succeded before but can't get it to work now... 

Regards
