I guess that makes it more complicated (and I need to check my > L2R privilege more often). Let me put it this way: if someone can find a clever algorithm to know, when we produce the line numbers, whether the "glyph row" will be "reversed" or not, we will be able to implement any number of niceties like the one discussed here, which produce asymmetric space before and after the line number. As things are, I simply couldn't find a solution for that (which doesn't mean it doesn't exist, just that I'm not smart enough to come up with one). Ideas and patches are welcome.
