Whoops, you are correct, Boyd.  I just logged into a VAX running
4.3BSD, and saw that happen (oddly enough, there's one at CMU you can
login to as guest.  Who knew?).

However, it looks like newer versions of vi fix the problem.  On my
FreeBSD machine at work, 10~ does the right thing [sic], and similarly
on the Sun I'm sending this mail from.

I'll agree though; a purely modal editor is just, well, weird.
