Committed, thanks. *Please* take a look at how what I committed differs from
what you submitted especially in terms of style - it's silly for me to spend
time fixing coding standards stuff while reviewing patches, and just 
means that
it takes me longer to get to them, instead of just committing them.

Thanks,
