Honestly, the way the question was phrased, I'd have assumed that it
wanted to group by month (not group by a group of months).  Jan 08 is
distinct from Jan 07.

Please accept my sincerest apologies if you you feel that I
misinterpreted the question.  I was merely trying to illustrate the
difference between what each approach was.
