Title: Fixed 80 chars marker does not appear in Firefox.

The background color of the 80-chars marker does not appear in Firefox. I tried several adjustments for z-index, height, position, etc.pp but no luck.

But luckily, it works with `border-left`, which achieves the exact same thing.

I skipped/dropped the rgb-without-alpha color, since we can rely on modern browsers.
