I've had a look, and I don't see the breaks from the convention. Can you say 
what commits and hunks?

I haven't tried to implement the XCode patch, but I removed the use from the 
cmLocalGenerator codepath.

I might be able to try making one at some point in the next few weeks, but 
if someone else can do that, it would be great.

Thanks,

Steve.
