Please format this stuff correctly.

Functions are declared like this:

static type NAME(TYPE ARG1, TYPE ARG2)
{
}

Noted and fixed.

You don't put the openning curly brace at the end of the line with the
closing parenthesis of the argument list.

Next, comments are to be formatted:

	/* Like
	 * this.
	 */

Well, to be fair, most comments in the existing code base actually use the style
I employed (in fact, I was copying it), so it seems like a blurry line at least.
