> 1. Evaluate this definition:
> (defun mouse-face-test ()
> (goto-char (point-min))
> (insert "aaaaaaaa")
> (let ((o (make-overlay (point-min) (point))))
> (overlay-put o 'invisible t)
> (overlay-put o 'after-string
> (concat (propertize "bbbb"
> 'face 'next-error
> 'mouse-face 'highlight)
> 2. Open a new buffer, type `M-x mouse-face-test'.
> 3. Hover the mouse cursor above the "b" letters. When the cursor is
> away, they're highlighted with the `next-error' face, and the "a"
> letters are untouched. But when the mouse hovers, the first of the "a"
> letters is also highlighted, with the `highlight' face. It shouldn't be.
