@media all minified?

hi,
I have a question regarding a "minified" serialization of e.g.

	@media all {a {color: red }}

I guess the following would not be the equivalent:

	@mediaall{a{color:red}}

as there is no space between @media and all and if tokenizing this it 
would lead to a single token ``@mediaall`` and not ``@media`` followed 
by ``all`` (from the spec: ATKEYWORD 	@{ident})?

I think it has to be:
	@media all{a{color:red}}

Safari nevertheless seems to acknowledge both, other browsers (IE7, FF3) 
do not.

Just to be sure I would like to ask the proper behaviour here.

thanks
Christof
