I'm not sure I understand. How is it possible to for ANYTHING to
happen after HEAD since HEAD is by definition the latest?
Do you mean that the rename could not be part of the changes in rev
10 (HEAD)? Why not?

No. I might try to compile that on my Mac later. (There is no way I
have time to set up to build on Windows.. too many uglies in the dev
environment there. I've done it once before and it wasn't fun
tracking down all the dependencies.)

Here it is, but I think it is working correctly. The problem is
perhaps in the documentation of peg revisions and what they are
capable of.
svnadmin create /tmp/repo
