All reports of source-contains-cvs-conflict-copy for the archive. The extended description of this tag is:
The upstream source contains a CVS conflict copy. These have file names like .#file.version and are generated by CVS when a conflict was detected when merging local changes with updates from a source repository. They're useful only while resolving the conflict and were probably included by accident. You may want to report this as an upstream bug.
This tag has not been emitted in any package tested by Lintian.
