Reference to local file that does not exists in github.css stylesheet

Thanks for this plugin! This is great. I was having trouble with my horizontal rules not showing up in my previews. Upon inspection, I found that at line 164 of github.css, there is a reference to a local file that github might have used when you copied the text over, but that doesn't exist in the package itself.

.page hr {
    background: transparent url('../../images/modules/pulls/dirty-shade.png') repeat-x 0 0;
    border: 0 none;
    color: #ccc;
    height: 4px;
    padding: 0;
}

I'm not sure if this was the source of my horizontal rules not showing up, but when I switched to a different stylesheet they showed up again! So I think this might be it. Hope this helps.
