Ahhh yes.  Now I remember this bug.  We had it in a paging program that
we have here.  I was able to fix it by making the program spit out a "\r"
after emitting the escape codes.  This only happened after prompts so the
fix worked fine.  This same fix should work for rn, I'll give it a try.
The 'stty tabs' fix does work, but it seems to screw up a few other things
a bit.

'rn' almost works as is, except that rn prints out the "ce" string just
before it continues after a prompt (with the actual text).  Putting in an
extra carriage return should solve the problem and not create any more.
Does this happen on other systems other than Suns?  Seems like it would
have to...
