Generally the cursor sits where the NEXT character will be added.  If
column 80 has just been filled you have 2 choices:
 1. Put the cursor on column 1 of the next line.
	Now if the next character is printable, it goes where the
	cursor is sitting.  That makes sense.  But if the next
	character is a NL, the cursor does not move.  That is not
	consistent or friendly.
 2. Make the cursor disappear.
	This handles the problem case with NL as mentioned above, but
	it is not friendly for the cursor to disappear.
I can't think of a way to do what you suggest in a way that is
consistent and friendly.
