- Properly display the value of totsize as unsigned. (DLR)
- If constant is TRUE, only display the cursor position when
disable_cursorpos is FALSE. Don't refuse to display it when
the cursor position hasn't changed, as that doesn't always

do_help()
- Don't treat NANO_CANCEL_KEY as NANO_EXIT_KEY anymore, for
