With ``--what=`` only the given path of the path is compared, e.g. ``--what=dirname`` causes only the dirname to be compared, ``--what=basename`` only the basename and ``--what=path`` causes the entire path to be compared (this is the default).
With ``--unique`` or ``-u`` the sort is deduplicated, meaning only the first of a run that have the same key is kept. So if you are sorting by basename, then only the first of each basename is used.
The sort used is stable, so sorting first by basename and then by dirname works and causes the files to be grouped according to directory.
It currently returns 0 if it was given any paths.
