HELP UPPERTOLOWER                                John Williams, May 1986

    uppertolower(<character|string|word>) -> <character|string|word>

This procedure converts uppercase characters to lowercase. If given a
string or word, every uppercase character in the sequence is converted to
lowercase. For example:

    uppertolower(`A`) =>
    ** 97                         ;;; i.e. `a`

    uppertolower('HELLO') =>
    ** hello

    uppertolower("JOHN") =>
    ** john

If the argument is not an uppercase character, string or word, it is
returned untouched:

    uppertolower(`a`) =>
    ** 97

    uppertolower([any old list]) =>
    ** [any old list]
