Media Queries operators fail

[raphaelgoetter]

Hello,

When some operators (such as , or and) are mixed in a media query, the parser doesn't guess when 2 MQ are the same.

For exemple :

@media print, screen {a {color: #f00}}
@media screen, print {a {color: #f00;}}

Should output :

@media print,screen{a{color:red}}

But the result is :

@media print,screen{a{color:red}}@media screen,print{a{color:red}}
