* 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
