Thanks Jason.  This brings up a very good point.  To be a completely
fair comparison, we should compare V3 keys against V4 pubkeys (and not
subkeys).  Since V4 keys are usually 2 or more V4 keys together, this
unfairly elevates the number of V4 keys.

So, using Jason's numbers for 2004-07-06, 9% of the keys are v2/v3 and
91% of the keys are v4.
