CompareEditorInputnull is returned no differences were found and no compare editor needs to be opened.
Progress should be reported to the given progress monitor.
A request to cancel the operation should be honored and acknowledged
by throwing InterruptedException.
Note: this method is typically called in a modal context thread which doesn't have a Display assigned. Implementors of this method shouldn't therefore allocated any SWT resources in this method.
