See if blank space before comment gofmt difference between 1.5, 1.6 is worth fixing.

E.g., the following .go file was considered "gofmt"ed in 1.5 but no longer so in 1.6:

package main

import (
    "fmt"
    "runtime"

    // Some comment.
)

func main() {
    fmt.Println(runtime.Version())
}

I was on the fence on this one for a while. One the one hand, the change in behavior is so insignificant, that spending time considering fixing it is probably not worth it. On the other hand, a gofmt regression is a pretty rare and interesting event, so perhaps it's worth to report (instead of forgetting) just because it may lead to interesting insights and lessons for future releases.

I tweeted about it and @adg suggested to just report it, so I've done so in golang/go#15294. This can be closed since it's being tracked there now.
