| 27 | * This is a issue of basic "vi" look-and-feel. Defining VI_MOVE works | |
| 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. | |
