Log:
  getbsize(3): clarify that underflow/overflow warnings in regard to $BLOCKSIZE
  gets output via warnx(3)
  
  This helps set expectations for how one might deal with those messages, i.e.,
  mute output from /dev/stderr today, since that's where vwarn(3) outputs messages
  to today.
  
  MFC after:	1 month
