This very large xorg-server patch wasn't to merge Wayland with X.Org, introduce some crazy new acceleration method, or really anything else of interest to end-users. Rather, this patch finally introduces a consistent coding style for the X.Org Server. This "Introduce a consistent coding style" patch was largely self-generated.
The mighty patch can be found here.
The work currently going into the xserver Git master will be for the X.Org Server 1.13 release, which is planned for release in early September with various changes.
