* Historic vi moved the cursor to the from MARK if it was before the current

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