Hmm, looks like we need this at inet_net_pton.c:499:

            else if (*src == '\0')
                goto enoent;
            if (tp + NS_INT16SZ > endp)
-                return (0);
+                goto enoent;
            *tp++ = (u_char) (val >> 8) & 0xff;
            *tp++ = (u_char) val & 0xff;
            saw_xdigit = 0;

A bit of googling suggests that this is equally broken in assorted
BSD distributions, which is likely where we got the code from
originally.  I wonder who we can report it to?
