* app.c (LEX_IS_PARALLEL_SEPARATOR): New macro. (IS_PARALLEL_SEPARATOR): New macro. (do_scrub_begin): Set up characters in tc_parallel_separator_chars as LEX_IS_PARALLEL_SEPARATOR, if it is defined. (do_scrub_chars): Handle LEX_PARALLEL_SEPARATOR chars like LEX_LINE_SEPARATOR except that we go to state 1 (as if the label has been seen).
