Ah. After checking the code I remember that this was right at some
point, but it was lost when the parsing step was made to use a table
(fillRelOptions). This behavior could be restored by having the fill
routine have a callback of some sort; we could use that to set a boolean
in StdRdOptions that indicated whether they are set in reloptions or are
default values.
