  - Add test for CloneWithCommitMsgHook
    
    The other CloneCommands are basically just factories whereas the
    CloneWithCommitMsgHook has logic for when parts of the command
    should or should not be added, and which combination of
    sub-commands are valid.
    To be able to confidently change the behavior of CloneWithCommitMsgHook
    a test that covers this logic is valuable.
