New AWS region in Germany announced today. git-annex doesn't support it yet, unless you're using the s3-aws branch.

I cleaned up that branch, got it building again, and re-tested it with testremote, and then fixed a problem the test suite found that was caused by some changes in the haskell aws library.

Unfortunately, s3-aws is not ready to be merged because of some cabal dependency problems involving dbus and random. I did go ahead and update Debian's haskell-aws package to cherry-pick from a newer version the change needed for Inernet Archive support, which allows building the s3-aws branch on Debian. Getting closer..
