73 | If operation is `insert-file-contents', the coding system is chosen based | |

96 | In these cases, the coding system initially will be `undecided'. |
97 | As the file is read in the DOS case, the coding system will be | |

99 | is read in the Unix case, the coding system will be changed to | |
100 | `undecided-unix' as LFs are detected. In both cases, | |
