As someone pointed to me off-list the above should be:
+ if (rf_one) {
+ (*write_ref)[targets] = xmemdupz(rf_one + 1, buf.len - (rf_one + 1 - buf.buf));
+ } else {
Or better:
+ if (rf_one) {
+ rf_one++; /* skip \t */
+ (*write_ref)[targets] = xmemdupz(rf_one, buf.buf + buf.len - rf_one);
+ } else {
Which is definitely more readable.
