I wonder, however, why we can't `git checkout -b bracket` and `test_when_finished "git checkout master"` and void those many `-C repo` options. But then, it is actually one of the shorter test cases, and pretty easy to understand. However, I would still like to see `test_tick`s before those `git commit` calls, to make the commit names reproducible. Thanks, Dscho
