If that proposal is accepted, I am willing to go through the code and
rename everything internally to match (and, in fact, would insist on
that happening).  But I think the current debate is primarily around
how we present this to users, so talking about the documentation seems
sufficient for the moment.

Well, that would be the same effective value under Robert's patch.
