[css] CSS::SAC fails to parse p:first-line

[Bjoern H. <der...@gm...>]

Hi Robin,

  I have a ruleset

  p:first-line { }

CSS::SAC fails to parse it. Around line 1000 

| # here we need to check whether the next token is also a selector
| # if it is, we need to make an AND_CONDITION containing the two selectors
| # and to attach it to a universal selector
| # then we'll have to mix it into the $cond below.
|     if (@tokens) {
|         eval { $tokens[0]->SelectorType };
|         if (!$@) {
|             my $and_cond = $sac->[_cf_]->create_and_condition($selector,shift @tokens);
|             $selector = $sac->[_sf_]->create_element_selector(undef,undef);
|         }
|     }

$and_cond is lost and $selector is useless from this point, thus one
gets

  bless([bless([9],'CSS::SAC::Selector::Element')],'CSS::SAC::SelectorList')

rather than what is expected. Thoughts?
