On comments, the specification says
    (http://golang.org/ref/spec#Comments): General comments start with the
    character sequence /* and continue through the character sequence */.
    A general comment containing one or more newlines acts like a newline,
    otherwise it acts like a space.
    
    Fixes golang/go#11528.
