To give OPT_FILENAME the prefix, we pass the prefix to parse_options() which passes the prefix to parse_options_start() which sets the prefix member of parse_opts_ctx accordingly. If there isn't a prefix in the calling context, passing NULL will suffice. Signed-off-by: Stephen Boyd <bebarino@gmail.com> Signed-off-by: Junio C Hamano <gitster@pobox.com>
