[CSS21] changing ~= space-separation to match css3-selectors

For a number of years, css3-selectors has said that ~= (and thus
also class selectors) match according to a whitespace-separated
list, not just a space-separated list.  This was changed between the
2001 CR and the 2005 LCWD:
http://www.w3.org/TR/2001/CR-css3-selectors-20011113/#attribute-representation
http://www.w3.org/TR/2005/WD-css3-selectors-20051215/#attribute-representation

We should change CSS 2.1 to match.
