We have some key bindings that print directly to the terminal while the user is still typing the command line. Thereafter, we redraw the command line, so the user can resume typing. To redraw a multiline command line, we first erase several lines above the cursor. To not erase the key bindings' output, we move the cursor down that many lines. Simplify the logic; no functional change.
