I see your point. You mean this:
Showing the cursor at where the next typed character
will be displayed.
Correct?
I agree that it is the best behaviour, but, yes, fixing
seems very difficult.
By the way, we will encouter this very tricky case, but it
seems ok to igore such a case.
(let (ov1 ov2)
(insert "abcdef")
(setq ov1 (make-overlay (- (point) 6) (- (point) 3) nil nil t))
(overlay-put ov1 'after-string "[hello]")
(setq ov2 (make-overlay (- (point) 3) (point)))
(overlay-put ov2 'before-string "[world]")
(forward-char -3)
(unwind-protect
(while t
(insert (read-char))
(message (format "%d-%d, %d-%d"
(overlay-start ov1) (overlay-end ov1)
(overlay-start ov2) (overlay-end ov2))))
(delete-overlay ov1)
(delete-overlay ov2)))
