I noticed a bunch of new warnings from nakedret today that coincide with #10 being merged. While that PR does report some real cases that were previously ignored, it seems to also flag returns in nested functions.

Take the following example module:

package x

func Dummy() (err error) {
	defer func() {
		// perform cleanup
		return
	}()
	return nil
}

I get the following output from the tool:

$ $GOPATH/bin/nakedret -l 5 x.go
x.go:6 Dummy naked returns on 6 line function 

While there is a naked return statement in Dummy's AST, it belongs to a nested function with no return values, so should not be reported.
