* Escaped newlines should also produce SyntaxError * Fix multiline comment parsing and add tests * Adapt makePredicate to handle \u2028 and \u2029 * Move up nlb check in regex so it's checked before any escape handling * Change error messages to conform ecma standard * Find_eol not recornizing \u2028 and \u2029 as line terminator * Remove \u180e as it is removed in unicode 6.3.0 from the category zs
