  23 # Make sure that tar -c correctly handles the case where a file is
  24 # encountered multiple times, even though it has a link count of 1.
  25 # This can occur when "tar -c FOO FOO" is used; it can also occur when
  26 # "tar -ch FOO" is used, if FOO contains symbolic links that point to
  27 # the same file.
