69 * Directory compare view is list-view based, so it shows one result (for
70 * folder or file, commonly called as 'item') in one line. User can select
71 * visible columns, re-order columns, sort by column etc.
73 * Actual data is stored in CDiffContext in CDirDoc. Dircompare items and
74 * CDiffContext items are linked by storing POSITION of CDiffContext item
75 * as CDirView listitem key.
