Looks all right.  I had the hbegin/hend somewhere else and I still didn't
get the right line, but this way it seems to work.  The other question is
whether we leave it up to the user to add it to the history with print -s.
I suppose that's all right here.

The point was probably to allow the editor to get hold of all the
characters.  You could probably bind ^D to accept-line to get pretty much
the same effect, but if you only wanted that on an empty line you would
need your own widget.

I missed the nslookup part out because I haven't applied the zpty patch.
I haven't applied that because I don't know if it's going to fail to
compile on some systems.  This may require some more configure tests.  But
it would be a nice library to have.
