    syscons - add sysctl to disable console bell globally
    
    Add sysctl `kern.syscons.enable_bell`, which globally disables the
    system console bell ("sc_beep") when set to 0. By default the bell is
    on.
    
    To silence all beeps, add this to /etc/sysctl.conf:
    
        kern.syscons.enable_bell=0
    
    This has the same effect as tcsh's "set nobeep". But there is no such
    setting to my knowledge for our "/bin/sh".
