Idea:

• instead of creating local tracking branches to support gitcr for branches, uses directly the commit from the remote branch or tag. This way we can achieve a general way of addressing commits to check out for the local clone in z2.
• Furthermore, it would be sufficient to do a shallow clone and reduced to a single history line.
