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