--------------------+-------------------------------------------------------
 Curses getstr prompts are dumb, and we need to teach it how to be a sane
 text editor. Arm's TextInputValidator class [1] supports the left/right
 arrows, home, end, and esc keys. We should add support there for the
 delete key too.

 This should be easy...
 - add a line here to log keycodes
 - run arm, navigate to the interpretor panel, hit the delete key
 - see in the log what the keycode is
 - add a handler for that keycode to delete the next character

 Another minor bug is that hitting backspace when at the start of the line
 deletes the first character.
