tweaks: stop recognizing escape sequences for a key without meaning

Nano does not do anything for the keystroke anyway (KEY_B2, the center
key on the numeric keypad, gets translated to ERR later on), so there
is no point in recognizing some of its escape sequences -- let those
sequences result in "Unknown sequence" instead.
