doc.Example should not worry about unresolved blank identifiers
https://golang.org/pkg/bufio/#example_Scanner_custom is not directly runnable in the playground via godoc, but if I copy+paste the code into https://play.golang.org/ then it runs just fine. This seems to be due to the blank identifier being considered unresolved in the following line in the example: _, err = strconv.ParseInt(string(token), 10, 32) But that's the whole point of blank identifiers- they're not supposed to be resolved. So let's skip adding the blank identifier to doc.playExample's unresolved map.
