Restore. * src/scan-gram.l (last_string): Is global to the file, not to yylex. * src/parse-gram.y (input): Don't append the epilogue here, (epilogue.opt): do it here, and free the scanner's obstack. * src/reader.c (epilogue_set): Rename as... (epilogue_augment): this. * data/c.m4 (b4_epilogue): Defaults to empty.
