The end of the buffer has a different color and a different character overlay depending upon where `point` is --- a leading cushion is used if the vertical column extends beyond the point at the end of the line.
It looks like overlays-in treats EOB specially, and does not treat
(point-max) in the same way. This is explicitly stated in the doc
string of overlays-in.
I don't know what are the reasons for such a special treatment, and
why a narrowed region doesn't get the same treatment. I always
thought that Emacs treats both the same. Perhaps all we need is to
give both the same treatment, and that's it.
Besides that, the doc string of remove-overlays is inaccurate and
misleading; I will take care of that.
