An overlay spanning 0 characters with a display property set to an
image displays the image (when the move-on-insertion properties of the
overlay ends are equal, it serves more or less as a visible marker).
It does not seem consistent if other display properties intended to
mask the underlying character range (even if empty) do not behave
likewise.
