From a quick look to one file, seems fairly consistent. Perhaps most unorthodox but at the same time easiest to justify: function bodies skip one level of indentation. The curly brace of function body at column zero is actually a separate, very traditional style. It's just that both styles apply to function bodies, there is no other causal relationship. Finally, indentation is 4 spaces, and tabs are expanded. Of course a very few places may be miss-styled, as happens with hand crafted code. While definitely sinful for not indenting with tabs as God intended, the style is not messy
