    """Check whether quote is truly end of a sentence.

    The end of a quotation may not be the end of the sentence. This function
    does a 'weak' test to find out: if the next non-whitespace character is
    lower case, then you don't have a full-sentence. As such, the quote
    does not mark the end of a sentence; set its position to -1.

    Args:
        pos (int): Relevant index near where quote detected.
        text (str): Text being parsed.

    Returns:
        -1 (int): if quote is not the end of the sentence.
        pos (int): if quote is the end of the sentence.
