For that matter, have a look at tree/visitors/to_css.rb, around line 67 - precisely the visit_directive method.

I'd use ruby-debug, by adding a debugger directive right after the two return statements and step through the code in order to better understand and change it. But from a quick look it seems that the change to implement what you're looking for should be located at line 73.

Have fun :-)
