Think I'm really finished with adjusted branches now. Fixed a bug in annex symlink calculation when merging into an adjusted branch. And, fixed a race condition involving a push of master from another repository.

While git annex adjust --unlock is reason enough to have adjusted branches, I do want to at some point look into implementing git annex adjust --hide-missing, and perhaps rewrite the view branches to use adjusted branches, which would allow for updating view branches when pulling from a remote.

Also, turns out Windows supports hard links, so I got annex.thin working on Windows, as well as a few other things that work better with hard links.
