Curses UI: fixed translation of the backspace key
* for historic reasons, the backspace key can be transmitted as
^H by the terminal. Some terminal emulators might do that - these
are fixed by this commit.
* Use CTL_KEY('H') instead of standard C '\b' as the former is less
ambiguous given the confusion around the backspace character.
