All reports of diff-contains-cvs-control-dir for the archive. The extended description of this tag is:
The Debian diff or native package contains files in a CVS directory. These are usually artifacts of the revision control system used by the Debian maintainer and not useful in a diff or native package. dpkg-source will automatically exclude these if it is passed -I or -i for native and non-native packages respectively.
Refer to the dpkg-source(1) manual page for details.
