Ah, I see what happened. I didn't clear out my patch directory prior to 
creating v7. In v7, I changed the commit message for patch 2. When I 
regenerated the patch set, all patches in my directory were overwritten 
except patch 2, so v6 of patch 2 was still present in the directory. 
When I sent an e-mail with everything from the directory, it sent v7 
patch 2 and v6 patch2. You can ignore the v6 patch 2 in the set.

Sorry for the confusion,
Mark!
