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. -- David Kastrup, Kriemhildstr. 15, 44793 Bochum
