I attached another patch to the ticket. It builds up the answer from the
empty map {} if the argument is a record (as the current select-keys does),
but from (empty map) if it is not a record, so it will preserve sortedness
of the argument. Not sure if there are any other cases that are a problem,
or if it does what everyone would expect, but it should be closer.
