I guess you want the cursor on the first character of the
overlay-string that is displayed first (leftmost)?  Are you asking how
to implement this when there are more than one overlay at EOB?

This seems to hint that you are talking about something different, so
maybe I misunderstand what you mean by "implement this" above?
