    """Return a copy of orig_dict updated with new_values.

    New keys are added, and the values of existing keys will take the
    values in new_values.

    You can specify more than one update dictionary.
    They are applied in order, so the values of any keys in later dictionaries
    will overwrite the earlier ones.
    If any evaluate to falselike (i.e. are None, False or empty)
    then they are skipped.
