[AUCTeX] user-keyword-class

[Per Eriksson]

Hello auctex mail list,

I'm using auctex 11.85 on aquamacs 1.9 and I have recently tried to  
make my own keyword
classes for highlighting latex syntax such as \citet{}, \citep{} and  
\citealp{}. I have used the semi-graphical interface to add a  
"keyword with specs" as an "command with arguments" ordering a  
foreground color change. This has resulted in that the keyword (e.g.  
\citet) is highlighted in purple while the argument(s) "[...]{...}"  
remain text black and not colored as I ordered.

Do anyone know why this happens and how to get the correct syntax  
highlighting on user added keyword ?

Best regards,
P. Eriksson
