Well, I did some googling, and the technical term I was thinking
of was "catastrophic cancellation". So how about
Note that some mathematical routines in such libraries could
suffer significant loss of accuracy, typically through so-called
"catastrophic cancellation", when this option is used to set the
precision to less than extended precision.
I think this is OK. So if nobody objects, this patch is OK for
mainline.
I'm sorry, but I don't have checkin privileges.
