1. There should be some comment saying that:
- This function is called for the document which the node
  previously belonged to.
- This function is called after the node is moved to a new
  document.

2. This function should not be declared at this line;
   functions at lines 688-690 and 692 are for mutations of
   Text nodes and not for node tree mutations. You probably
   should move this function to somewhere near lines 681-685
   and also should follow the naming convention of the
   functions there.

3. "New" -> "Another", maybe? The target document may not
   be necessarily new.

I renamed the function to |updateRangesAfterNodeMovedToAnotherDocument|.
