46 * This is an issue of basic "vi" look-and-feel. Defining VI_MOVE works
47 * like real vi: i.e. the transition from command<->insert modes moves
48 * the cursor.
49 *
50 * On the other hand we really don't want to move the cursor, because
51 * all the editing commands don't include the character under the cursor.
52 * Probably the best fix is to make all the editing commands aware of
53 * this fact.
