Does it work that way for you? For me the default non-propertized overlay always shows the cursor at the end, regardless of which direction I arrived from.

Here's the test file I used:

```
ABEF

(defun test-overlay-cursor (completion pt)
   (remove-overlays)
   (save-excursion
     (let* ((p-completion (propertize completion 'face 'error))
            (ov (make-overlay pt pt nil t t)))
       (overlay-put ov 'display "")
       (overlay-put ov 'after-string p-completion)))
   (goto-char 0))
(test-overlay-cursor "CD" 3)
```

I can navigate so I see "AB{CD}<cursor>EF" or "A<cusor>B{CD}EF", but I can't get the cursor to be before the overlay: "AB<cursor>{CD}EF".

Of course one can add properties to the overlay to get the cursor be positioned always in front, but then you can't get to show it at end.

The main point of the discussion is that it would be nice if it would be possible use usual navigation commands to get from "AB<cusror>{CD}EF" to "AB{CD}<cusor>EF".
