Do we really have to go through this void * stage?

Also, please stop reindenting the arguments. I tend to just switch to
two tabs, but lining them up with the opening bracket leads to extra
churn. Either leave them alone for the entire series or switch _once_.

I wish the coding style would at least recommend something -- I know, different subsystems/files have their own rules. Nowadays, I prefer 2 tabs as well.
