Well, not totally irrelevant, I just reserve the right to ignore Eric

My preference tends to be the other way around; I think putting the rc
assignment in the if block makes the code more readable and that is
how I tend to write things. That said, I don't recall ever requiring
someone to redo a patch only because of this style nit ... if I did,
shame on me.

I do appreciate all the patches, thank you! However, a bit of a
warning that it may take me a little bit of time to work my way
through reviewing and merging all of them.
