    type T byte
    func (T) String() string { return "X" }
    
    fmt.Sprintf("%s", []T{97, 98, 99, 100}) == "abcd"
    fmt.Sprintf("%x", []T{97, 98, 99, 100}) == "61626364"
    fmt.Sprintf("%v", []T{97, 98, 99, 100}) == "[X X X X]"
    
    This change makes the last case print correctly.
    Before, it would have been "[97 98 99 100]".
    
    Fixes #8360.
