I think this would be better formatted as:

	if (...)
		...
	else if (...)
		...
	else
		...

We don't indent unless there's braces, and if there's braces, coding
style advises braces on both sides of the "else". So, much better to
use the formatting I suggest above.

Apart from that, nothing stands out as being wrong in this patch.

Thanks.
