28  * like real vi: i.e. the transition from command<->insert modes moves
29  * the cursor.
30  *
31  * On the other hand we really don't want to move the cursor, because
32  * all the editing commands don't include the character under the cursor.
33  * Probably the best fix is to make all the editing commands aware of
34  * this fact.
