provide copy contructor and operator = for lexical_feedback class.
* lex.h, lex.ll (lexical_feedback::lexical_feedback): Provide copy
constructor. Correctly initialize looking_at_anon_fcn_args to false.
(lexical_feedback::operator=): New function.
(lexical_feedback::init): Simplify.
(reset_parser): Assign new lexical_feedback object to global
lexer_flags instead of calling init on existing object.
