using MC, whether 4.8.22 in Leap 15.1, 4.8.21 in Fedora 30, or 4.8.23 in
Tumbleweed, all directories in CONTENTS.cpio are non-empty. This is expected
behavior.

(downloaded with zypper)
all directories are displayed as empty, not expected behavior.

Is there a compression scheme missing from mc packaging that causes this?
Does mc.ext need some sort of customization? Something else? Bug report?
