2.5.5

The -C option isn't available in versions of git older than 1.8.5, and officially we only require git 1.8.3.1 or newer (and the latter is the version you'll find on CentOS 7, so the test fails there). In any case we can simply specify the working directory to runCmd() so just do that instead.
