An Ultrix 4.2 (DEC 5000/200) /dev/MAKEDEV has an
expr regex with a leading  "," (comma), which makes no
sense to me:

  for fullname
  do

  tryname=`expr $fullname : ',*\(.[a-zA-Z]*\)'`
  tryunit=`expr $fullname : '[^0-9]*\([0-9]*\)'`
  trypart=`expr $fullname : '[^0-9]*[0-9]*\(.*\)'`
  if test $silent -eq 0 ; then
	  echo "MAKEDEV: special file(s) for "$fullname": "
  fi

Is this a typo lurking in the distributed MAKEDEV?
