Code reformatting, unless 100% automatic with a 100% proven and C99

So did many when reiser 3 was fresh, it was much raved about its speed,
stability, its alleged recoverability and recovery speed, and then
people started sending full filesystem dumps on tape and other media to
It's impossible to fully test nontrivial code, every option, every
