  Log:
  SVN rev 212390 on 2010-09-09 21:59:53Z by jilles
  
  expr(1): Add sh(1) versions of examples, remove an incorrect example.
  
  The three examples are better done using sh(1) itself these days.
  
  The example
    expr -- "$a" : ".*"
  is incorrect in the general case, as "$a" may be an operator.
  
  MFC after:      2 weeks
