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