Sounds sensible to get rid of the estimation with the Datum size
requirement and never give up with the abbreviated key sort, as done
in 0001. I'd leave the code touched by 0002 remain as-is.

@Tom, why didn't you consider that as a continuation of 6aebedc38497?
Just to keep the changes with SIZEOF_DATUM < 8 leaner, or just because
it was not worth bothering based on your TODO list? I am wondering if
there is a reason I may be missing here.
