What did you do?

package main

import (
	"fmt"
)

func main() {
	fmt.Sprintf("my first input %s with my second input %s with a really long string i want on two lines "+
		"should pass linting for my third input %s", "cat", "dog", "turtle")
}

What did you expect to see?

gotvet should pass

What did you see instead?

The above should pass linting but it fails because the last %s is on a different line with:

server/server.go:216:4: Sprintf format %s arg err.Error is a func value, not called (govet)
			fmt.Sprintf("my first input %s with my second input %s with a really long string i want on two lines "+
			^
make: *** [lint] Error 1

Oops missed my () on Error.
