* Historic vi moved the cursor to the from MARK if it was before the current |
32 |
|
|
* cursor and on a different line, e.g., "yk" moves the cursor but "yj" and |
33 |
|
|
* "yl" do not. Unfortunately, it's too late to change this now. Matching |
34 |
|
|
* the historic semantics isn't easy. The line number was always changed and |
35 |
|
|
* column movement was usually relative. However, "y'a" moved the cursor to |
36 |
|
|
* the first non-blank of the line marked by a, while "y`a" moved the cursor |
37 |
|
|
* to the line and column marked by a. Hopefully, the motion component code |
38 |
|
|
* got it right... Unlike delete, we make no adjustments here. |
