 For the **reverse wrap** (non-extended) behavior, moe the cursor to the left `n`

+leftmost boundary, if `n > 0` and the previous line was wrapped, then move the
+cursor to the [right margin](#TODO) of the line above the cursor. If the previous
+line was not wrapped, the cursor left operation is complete even if there

 This wrapping mode does not wrap the cursor row back to the bottom margin.
