format-patch: use OPT_STRING_LIST for to/cc options
The to_callback() and cc_callback() functions are identical to the generic parse_opt_string_list() function (except that they don't handle optional arguments, but that's OK because their callers do not use the OPTARG flag). Let's simplify the code by using OPT_STRING_LIST. Signed-off-by: Jeff King <peff@peff.net> Signed-off-by: Junio C Hamano <gitster@pobox.com>
