Sorry, I'm going to reject this one.  I applied the patch and looked at the generated docs, finding them to be less readable than before.  AFAICT, we've had no issues with people mis-reading the text as currently presented.   Also, I looked back at the underlying spec, http://speleotrove.com/decimal/daops.html , and found that it tended to refer to first and second operand.  I would like to keep our docs as close to that as possible.
