10.2-BETA1: pw(8) does not support "pw useradd name -u 0"

In our system build scripts we have this command:

/usr/sbin/pw -V $d useradd toor -u 0 -g 0 -d /root -s /bin/sh -c "Bourne-again Superuser" -g wheel -o

After 10.2-BETA1, the toor account is being added with UID 1001 instead of UID 0. This looks like a problem with line 754 in pw_user.c, which has this test:

         * Check the given uid, if any
        if (id > 0) {
                uid = (uid_t) id;

                if ((pwd = GETPWUID(uid)) != NULL && conf.checkduplicate)
                        errx(EX_DATAERR, "uid `%u' has already been allocated", pwd->pw_uid);
        } else {
                struct bitmap   bm;

The (id > 0) test should probably be (id >= 0) to allow “-u 0” to be passed on the command line.

This change is from r285092 by bapt at . Was this change in behaviour intentional?
