Bug 141192 [Viewers] Javadoc change about multiple equal elements in StructuredViewer and AbstractTreeViewer
bundles/org.eclipse.jface/src/org/eclipse/jface/viewers/AbstractTreeViewer.java
* Compare the two elements using the given sorter. If the
	 * sorter is a {@link TreePathViewerSorter}, the provided
	 * tree path will be used. If the tree path is null and the
	 * sorter is a tree path sorter, then the elements are root elements
	 * @param sorter the sorter
	 * @param parentPath the path of the elements' parent
	 * @param e1 the first element
	 * @param e2 the seocnd element
	 * @return the result of comparing the two elements
