I put them in, probably for consistency if the log is changed to something else that's not magical. IIRC one of the magic stdlib \n-adders used to do another Write, but package log is doing an append before the Write. https://golang.org/src/log/log.go?#L169

Not a bad idea.

In fact log here is from github.com/op/go-logging (https://github.com/release-engineering/backvendor/blob/master/backvendor/gosource.go#L31).
