    """Get extra, changed and missing files from a dircmp results object.

    From dircmp results find:
        1. Any files that differ.
        2. Extra files in left that are not in right.
        3. Missing files that are in right but not in left.
    Recursively enter sub directories to continue search.

    When searching for extra files, certain files and directories that are
    user modifiable should be ignored. For example, 'wp-content/themes' will
    likely contain unique files that will not appear in a new copy of the
    same WordPress version. These should be ignored to avoid giving false
    positives.
