pkt-line: check write_in_full() errors against "< 0"
As with the previous two commits, we prefer to check write_in_full()'s return value to see if it is negative, rather than comparing it to the input length. These cases actually flip the logic to check for success, making conversion a little different than in other cases. We could of course write: if (write_in_full(...) >= 0) return 0; return error(...); But our usual method of spelling write() error checks is just "< 0". So let's flip the logic for each of these conditionals to our usual style.
