maybe it is the best to ignore the residue field completely and
calculate for oneself.  This removes the need of reading the additional
information from the transfer result data and the check if the residue
and the calculated residue are the same.

Even though Linux has a quirk for that, Darwin [1] just ignores this
and I think it is a good idea.  Haiku [2] ignores the residue, too, and
calculates it by itself.  Nobody seems to have a problem there.
