Revision: 21147
Author:   [email protected]
Date:     Mon May  5 15:16:26 2014 UTC
Log:      Remove old branch logic from push scripts.

The old temporary branch is not needed anymore. All scripts create a different branch after creating the temporary branch.

This also fixes logging subprocesses and logs a warning to track down script failures due to wrong branches.
