Were we to design it from scratch, I would be in favor of this, but as this
has been in the wild for quite some time, we now have to deal with  
I suspect this kind of comment between "and" and the opening parenthesis  
is pretty
rare, so that might be ok, but still, making correct style sheets  
incorrect is
not something we should do without careful consideration.
