There are several places where white space seems to have been
left out of the grammar.

Unless I'm missing something we need to replace
   : selector [ COMMA S* selector ]*
with
   : selector [ S* COMMA S* selector ]*
and
   : PLUS S* | GREATER S* | TILDE S* | S+
with
   : S* PLUS S* | S* GREATER S* | S* TILDE S* | S+

Bert or dbaron, could you check that? If it's correct I'll
edit these changes into the spec.
