Not true about "numeric". This is the code:

                /* 2nd field: uid:gid - device ownership */
                {
                        struct passwd *pass;
                        struct group *grp;
                        char *str_uid = tokens[1];
                        char *str_gid = strchrnul(str_uid, ':');

                        if (*str_gid)
                                *str_gid++ = '\0';
                        /* Parse UID */
                        pass = getpwnam(str_uid);
                        if (pass)
                                uid = pass->pw_uid;
                        else
                                uid = strtoul(str_uid, NULL, 10);
                        /* Parse GID */
                        grp = getgrnam(str_gid);
                        if (grp)
                                gid = grp->gr_gid;
                        else
                                gid = strtoul(str_gid, NULL, 10);
                }

It does allow USER:GROUP syntax where either can be a user/group name,
not numeric ID.
