It's suposed to be a single token. I just updated section 7.7 in my working draft of the ES6 spec. to make this explicit.

Is "..." a new token that should be listed in Punctuator. I think it should and it seems like a little miss for which I am happy to file a bug, but I am not so sure as the proposal[1] doesn't include it.
It seems that Firefox implements it as a token. Test cases:
function x(. ..y) {}
function x(./**/..y) {}
. Both throw SyntaxError in Firefox 17.

Test cases: function x(. ..y) {} function x(./**/..y) {} . Both throw SyntaxError in Firefox 17.
