 * 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.
