tooltip-mode = nil only displays first line of multi-line text-properties or overlays

[M Jared Finder]

If you have tooltip-mode disabled, multi-line help-echo text-properties and 
overlays only display
their first line.  Here's some code that reproduces the behavior:

(let* ((min (point-min))
       (max (point-max))
       (half (/ (+ min max) 2)))
  (let ((overlay (make-overlay min half)))
    (overlay-put overlay 'help-echo "Multi\nLine\nhelp"))
  (put-text-property half max 'help-echo "Even\nmore\nmulti\nline\nhelp"))

This is *not* a problem if tooltip-mode is on and tooltip-use-echo-area=t.
