All reports of source-contains-hg-control-dir for the archive. The extended description of this tag is:
The upstream source contains a .hg directory. It was most likely included by accident since hg version control directories usually don't belong in releases and may contain a complete copy of the repository. If an upstream release tarball contains .hg directories, you should usually report this as a bug upstream.
This tag has not been emitted in any package tested by Lintian.
