  SVN rev 182444 on 2008-08-29 15:02:50Z by ed
  
  Backport two small fixes from the MPSAFE TTY branch in Perforce:
  
  - Implement IMAXBEL. It turned out the IMAXBEL termios switch was marked
    as supported, while it had not been implemented.
  
  - Don't go into the high watermark when in canonical mode, no data has
    been canonicalized and the input buffer is full. This caused the
    terminal to lock up. This prevented users from pressing
    backspace/^U/etc in such cases.
  
    This could easily be simulated by pasting a very big amount of data in
    a shell with sh(1) in canonical mode.
