52 * This is an issue of basic "vi" look-and-feel. Defining VI_MOVE works
53 * like real vi: i.e. the transition from command<->insert modes moves
54 * the cursor.
55 *
56 * On the other hand we really don't want to move the cursor, because
57 * all the editing commands don't include the character under the cursor.
58 * Probably the best fix is to make all the editing commands aware of
59 * this fact.
