Oh cool! Thanks for digging in. It's always interesting to me how many "accidental features" there are lurking in code where every behavior isn't necessarily defined. In this case though, it was an explicit choice which is awesome.

On a side note, what an interesting formatting style. I don't read a ton of C, but choices on what brackets/parens require spaces and what ones don't seem almost opposite to what I'm used to. Easy enough to read still though.
