move global parser_end_of_input variable to lexical_feedback class * lex.h, lex.ll (parser_end_of_input): Move global variable to lexical_feedback class. Change all uses. (reset_parser): Don't reset parser_end_of_input here. * oct-parse.yy (eval_string, parse_fcn_file): Add lexer_flags object to unwind_protect stack. Don't protect parser_end_of_input.
