Install error

I'm getting the following error on install. I'm new to Go, so I'm not 100% sure that my purposed fix is correct, but I think it will work. I figured you could treat this PR as a bug, if it's not quite right.

# github.com/onsi/ginkgo/stenographer
/usr/lib/go/src/pkg/github.com/onsi/ginkgo/stenographer/console_logging.go:13: function ends without a return statement
