overlay before- and after-string and mouse-face |

This bug is extracted from #1176, which contained several issues.
The mouse-face property of an overlay with a display string does not
affect any before-string, but it does affect the after-string.
This can be worked around to some extent by copying the mouse-face
property to the before-string, but one cannot get the whole overlay
highlighted at one time.
Example:
(let ((buff (generate-new-buffer "overlay test"))
o)
(with-current-buffer buff
(insert "text")
(setq o (make-overlay (point-min) (point-max)))
(overlay-put o 'mouse-face '(:background "green"))
(overlay-put o 'display "display")
(overlay-put o 'before-string "before string")
(overlay-put o 'after-string "after string")
(pop-to-buffer buff)))
"displayafter string" has mouse-face, but "before string" does not.

I've checked a fix for this into the trunk.
