Log:
  MFC r281785
  
  Always send log(9) messages to the message buffer.
  
  It is truer to the semantics of logging for messages to *always*
  go to the message buffer, where they can eventually be collected
  and, in fact, be put into a log file.
  
  This restores the behavior prior to r70239, which seems to have
  changed it inadvertently.
