That common path is stripped and the contents are extracted to ``target_dir``, similar to passing ``-C {target} --strip-components 1`` to the ``tar`` command.

The last, innermost context manager may take arbitrary arguments, but each successive context manager should accept the result from the previous as a single parameter.
