Summary:
The documentation leads me to believe that the before-string and
display properties of an overlay should be orthogonal. However, the
before-string is not displayed if the display property is the empty
string.
Reproduce by evaluating this code:
(let ((buf (get-buffer-create "foo")))
(with-current-buffer buf
(display-buffer buf)
(erase-buffer)
(dolist (o (overlays-in (point-min) (point-max)))
(delete-overlay o))
(insert "ABC")
(let ((o (make-overlay 2 3))
(s (make-string 3 ?X)))
(overlay-put o 'display "")
(overlay-put o 'before-string s))))
You will see the 'foo' window pop up and in the window you will see
'AC'. I expected that instead 'AXXXC' would be shown.

This bug is already fixed in current CVS (and in the Emacs 23.1 branch).
