    stat: Nits in stat tests
    
    * Use ourselves as test file instead of /COPYRIGHT, which may or may not
      be present in the test environment.
    
    * atf-check understands \n in strings, use it.
    
    * Some file systems don't like creating small holes, so create large ones
      instead.  This means we need two variables: ps (page size) is the
      minimum size of a data region and the alignment for a hole, while hs
      (hole size) is the minimum size of the holes we create.  This makes no
      difference on FreeBSD but makes it easier to port the test to other
      platforms.
