I don't believe in "documenting bugs". Bugs should be fixed,
not treated as permanent.
Would someone please debug this?
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
Reproduce by evaluating this code:
(let ((buf (get-buffer-create "foo")))
(dolist (o (overlays-in (point-min) (point-max)))
(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.

It works fine with after-string.
