Simplify cursor movement for multi-line prompts before repainting

Browse source 
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.
