ran the formatter.  Many of the changes for this file are generally negative.
Not surprisingly, this file is a formatter torture test. A few of the comments
are now in the wrong place and the text density is painfully low at times. 
On the positive side, the way the formatter places all optional parameters on
the same line is nice.
