Hello everybody,
for syntax highlighting of config files, I have something like this in my /etc/joe/ftyperc:

*.conf
-autoindent
-syntax conf
-pound_comment

that works fine, but does not highlight c-style comments 
/* comment */

I have tryied to add:

-c_comment

but that does not seem to have any effect

could anybody please advise how to do it ?

many thanks,
konrad
