Re : Re : [css3-values] nesting calc()

Ok, you just answered my initial question. I don't mind about spaces
between function name and function arguments, nobody would actually
want to use that, I think. However, I wasn't sure the CSS Parser actually
considered whitespaces. 
 
In such case, I don't have any concern about using parentheses directly.
