OMG, my first sizable haskell patch!
So trying this out..
In each repo I want to sync, I first `git branch synced/master`
Then in each repo, I found I had to pull from each of its remotes, to get the tracking branches that `defaultSyncRemotes` looks for to know those remotes are syncable. This was the surprising thing for me, I had expected sync to somehow work out which remotes were syncable without my explicit pull. And it was not very obvious that sync was not doing its thing before I did that, since it still does a lot of \"stuff\".
Once set up properly, `git annex sync` fetches from each remote, merges, and then pushes to each remote that has a synced branch. Changes propigate around even when some links are one-directional. Cool!
So it works fine, but I think more needs to be done to make setting up syncing easier. Ideally, all a user would need to do is run \"git annex sync\" and it syncs from all remotes, without needing to manually set up the synced/master branch.
While this would lose the ability to control which remotes are synced, I think that being able to `git annex sync origin` and only sync from/to origin is sufficient, for the centralized use case.

Code review:
Why did you make `branch` strict?
There is a bit of a bug in your use of Command.Merge.start. The git-annex branch merge code only runs once per git-annex run, and often this comes before sync fetches from the remotes, leading to a push conflict. I've fixed this in my \"sync\" branch, along with a few other minor things.
`mergeRemote` merges from `refs/remotes/foo/synced/master`. But that will only be up-to-date if `git annex sync` has recently been run there. Is there any reason it couldn't merge from `refs/remotes/foo/master`?

I have made a new `autosync` branch, where all that the user needs to do is run `git annex sync` and it automatically sets up the synced/master branch. I find this very easy to use, what do you think?
Note that `autosync` is also pretty smart about not running commands like \"git merge\" and \"git push\" when they would not do anything. So you may find `git annex sync` not showing all the steps you'd expect. The only step a sync always performs now is pulling from the remotes.

I'm confused by the fact that the git-annex-shell adc rejects any repo names that don't start with /~/ since none of my repos start that way. It seems work ok if I just delete /\~ from the front of the regex, but I feel like I must be missing something.
