Apart from renaming `tbdiff` to `range-diff`, only one test case needed to be adjusted: 11 - 'changed message'. The underlying reason it had to be adjusted is that diff generation is sometimes ambiguous. In this case, a comment line and an empty line are added, but it is ambiguous whether they were added after the existing empty line, or whether an empty line and the comment line are added *before* the existing empty line. And apparently xdiff picks a different option here than Python's difflib.
