Hmm, had to read that a few times before I saw what you meant regarding 'v2' 
as the revised commit.

Exactly. The latter.

I certainly hadn't picked up on that ability to use the extended sha1 syntax 
(specifying revisions...) here.

Part of the issue is that the whole fixup/squash capability is buried within 
just two documents as asides [1], and in the place it's spelt out (in 
rebase) it talks about the commit message being used, which is just part of 
the confusion.

[1] just looked at the new Progit version and fixup/squash is not even 
mentioned.
