Wildcards broken?

[flowchartsman]

This library does not properly parse wildcards, it seems:

Using the following code:

package main
import (
    "github.com/joeguo/tldextract"
    "fmt"
)

func main() {
    var test string
    var err error
    tld, _:= tldextract.New("/tmp/tldcache.txt",false)

    for err == nil {
        fmt.Printf("string: ")
        fmt.Scanf("%s\n", &test)
        result := tld.Extract(test)
        if result.Flag == tldextract.Malformed {
            fmt.Println("Error", result)
        } else {
            fmt.Printf("%s.%s\n", result.Root, result.Tld)
        }
    }
}

I get:

string: http://foo.bar.com
bar.com
string: http://foo.co.uk
Error &{0   }
string: http://foo.*.uk
foo.*.uk

The "foo.*.uk" is most certainly incorrect.
