Does this matter at all? We use the explicit notation in quite a number
of places and it works great. I'd like to avoid needless churn unless
there is a very good reason to switch.

Also this contains whitespace changes that remove the extra level of
indentation that is used to separate register field definitions from the
register definitions.
