When having a zero-width pattern inside the assertion it doesn't matter in which direction you look. It's zero width. It's like saying that you jump 0 meters up in the air, or 0 meters down into the ground. You're still not moving. Sure, it might make more sense to say you jumped 0 meter up from the ground than down in the ground, but effectively it's still the same thing.

I used look-ahead because if I recall correct it's faster, and it was supposted to be fast. Plus it's one byte shorter, and he wanted prettiness. I consider (?!) prettier than (?<!).
