gofmt does some strange linebreaks

<pre>Given this source code:

if writer, err = os.Open(outfile, s.O_WRONLY|os.O_CREATE|
        os.O_TRUNC, 0666); err != nil {
    log.Fatal(err)
}

gofmt -tabwidth=4 -tabindent=false

Produces:

if writer, err = os.Open(outfile,os.O_WRONLY|os.O_CREATE|
    os.O_TRUNC,
    0666); err != nil {
    log.Fatal(err)
}

Notice the newline inserted before the file permissions.</pre>
