51 * This is an issue of basic "vi" look-and-feel. Defining VI_MOVE works

53 * the cursor.
54 *
55 * On the other hand we really don't want to move the cursor, because
56 * all the editing commands don't include the character under the cursor.
57 * Probably the best fix is to make all the editing commands aware of
58 * this fact.
