It is supposed to be the overlay start and end, but uses the overlay that
has been put at the character in the help buffer instead of the original
overlay.  This was apparently a deliberate choice so that you can do C-u
C-x = on a character in the *Help* buffer and still get information on the
text properties and overlays:

	* descr-text.el (describe-char): Copy the character with text
	properties and overlays into the first line, and call
	describe-text-properties on it.

Unfortunately that has the side effect of losing the original overlay
position.
