`zb` ghost cursor

[nullromo]

When using zb or z-, vim scrolls until the current line is at the bottom of the window. This plugin does not interfere with that functionality, but when you use zb you get a strange behavior. The cursor appears to be in the same place it was in before, but the actual virtual cursor position is where it ought to be. So if you zb and then j, everything will be normal. If you zb and then i, it will be normal. It's just the positioning of where the cursor gets drawn after zb is not right.
