[Neil Williams]

Package: devscripts
Version: 2.16.1
Severity: normal
File: /usr/bin/dcmd

$ dcmd ls -1 ../build-area/lava-server_2016.3-3~bpo8+1_amd64.changes

../build-area/lava-server-doc_2016.3-3~bpo8+1_all.deb

../build-area/lava-server_2016.3-3~bpo8+1.dsc is listed twice despite only appearing
as a single listing with checksums:
