  SVN rev 216547 on 2010-12-18 23:03:51Z by jilles
  
  sh: arith: Disallow decimal constants starting with 0 (containing 8 or 9).
  
  Constants in arithmetic starting with 0 should be octal only.
  
  This avoids the following highly puzzling result:
    $ echo $((018-017))
    3
  by making it an error instead.
