Title: The "branch:sync" command output shows error when no error found

I run `gush b:s` inside Gush repo clone and get following output (see image):
![gush_branchsync_output](https://cloud.githubusercontent.com/assets/1277526/2832715/b7b78f0c-cfc7-11e3-97ea-e23e32aa1a19.png)

I don't know what determines if there is yellow `OUT>` or red `ERR>` prefix before line but it clearly reports good stuff like regular Git output as errors.
