C-U prompting

[David L. Andre <DLA at SCRC-TENEX>]

My previous curt response was due to the fact that I had to leave to go
skiing in 5 minutes.  Now that I have time, I will elaborate.  The only
thing that hasn't been said by others which still bothers me is that the
numeric arg thing appears in the typein window sometimes, and over the
mode line at others.  I didn't like the duplicity of seeing C-U's all
over the bottom of my screen.  I would prefer to see it go over the mode
line, because that's where I'm use to seeing it.

I also think the whostate should be TYI, not TYPEAHEAD.  There should be
no distinction from the user's point of view, and it scares me when the
whostate starts doing wierd things.  (ie, I stop and try to figure out
what's going on.)
