[selectors4] Redundant regexp in the grammar

Hi,

The lexical scanner for selectors includes {nonascii} in its string1, 
string2, invalid1 and invalid2 macros but this is unnecessary: all 
non-ASCII characters are already matched by [^\n\r\f\\']

The same problem exists in selectors3, but not in css21.

Regards,
