Fix arguments to bulk Index call in documentation
Call to Sprintf malformed

See: http://play.golang.org/p/OoZfNXBmHA

For just indices, a single '%s' suffices. I think the second '%s' may have been intended for params (http://www.elasticsearch.org/guide/en/elasticsearch/reference/current/cluster-health.html), but adding those as an argument to the Health function would be a breaking API change. Let me know if you would like that change made to the API.
Replaced "error" with "res_err"

"error" is a reserved keyword in Go. Using "error" as a variable, although possible, is ill-advised.
