- we don't properly handle ctrl-c in ReadConsole with control block
  + this revisits ctrl-break (or ctrl-break from unix console) to
    map it unconditionnaly of console mode (as native does) to a
    windows ctrl event
  + and transfer to windows layers the management of ctrl-c
    (for a unix console when ENABLE_PROCESSED_INPUT isn't set)
