    """Compare the contents of two fiff files using diff and show_fiff

    Parameters
    ----------
    fname_1 : str
        First file to compare.
    fname_2 : str
        Second file to compare.
    fname_out : str | None
        Filename to store the resulting diff. If None, a temporary
        file will be created.
    show : bool
        If True, show the resulting diff in a new tab in a web browser.
    indent : str
        How to indent the lines.
    read_limit : int
        Max number of bytes of data to read from a tag. Can be np.inf
        to always read all data (helps test read completion).
    max_str : int
        Max number of characters of string representation to print for
        each tag's data.
    verbose : bool, str, int, or None
        If not None, override default verbose level (see mne.verbose).

    Returns
    -------
    fname_out : str
        The filename used for storing the diff. Could be useful for
        when a temporary file is used.
