coverage 4.0 added support for skip_covered option in the [report] section.

skip_covered (boolean, default False): Don’t include files in the report that are 100% covered files. See Coverage summary for more information.[1]

This lib doesn't seem to recognise and pass this parameter to the coverage runner.

Best.
