I don't like this function at all, but it's basically a trick to get the input's mp_log instance in a case the mp_input_parse_cmd_strv() is almost certainly not going to output anything. But still make it somewhat more consistent with mp_input_parse_cmd_strv() - why force the caller to always use MP_ON_OSD_AUTO?
