If three developers on the mailing list can't agree, chances are at
least one user will be unhappy with whatever we decide.

I personally find it very surprising that pasting would interact with
the region in any way at all, yanking normally doesn't. If this is
some special vi thing, maybe it should only be replaced in vi mode. I
don't think the region and pasted text have anything in common or are
"almost the same thing", and I don't think they should be, unless we
also make yanked text act the same way, which I also don't think we
should.

(My interest here is mostly academic since I won't use any of this
builtin behavior. I would personally prefer if nothing gets deleted,
nothing gets stripped, and generally nothing in general happens except
the text gets pasted, like I asked it to be. I don't think anyone ever
complained to me about the behavior of the widget I made, but then
again, they all added it on purpose).

We have at least two options that decide if and how we print a single
newline before drawing the prompt, maybe there is room for some here
as well.
