1 array element missed

In this example
`var s = "www.google.com".toSlice();`
`    var delim = ".".toSlice();`
`    var parts = new string[](s.count(delim) + 1);`

parts should contain three elements `www` / `google` / `com` but there are only two dots in `www.google.com` string.
(count + 1) is required instead of (count) if we want all three parts of the string to be in `parts` array.
