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

92 | If operation is `write-region', the coding system is chosen based |

97 | The most common situation is when DOS and Unix files are read and |
98 | written, and their names do not match in `untranslated-filesystem-list'. | |

100 | As the file is read in the DOS case, the coding system will be | |
101 | changed to `undecided-dos' as CR/LFs are detected. As the file | |
102 | is read in the Unix case, the coding system will be changed to | |
103 | `undecided-unix' as LFs are detected. In both cases, | |
104 | `buffer-file-coding-system' will be set to the appropriate coding | |
105 | system, and the value of `buffer-file-coding-system' will be used | |
