    getty(8): Sync with FreeBSD.
    
    * Change gettytab's 'he' capability to accept a POSIX extended regexp
      to mess with the system's hostname better (r313107).
    
    * Add a new 'iM' capability to specify a program to be run that
      generates the banner message displayed before the login prompt.
      This extends the functionality of 'im'.
    
    * Do not loop indefinitely if the device node doesn't exist (think
      USB serial adapters e.g.).
    
    * Various bug fixes and minor issue adjustments.
