All reports of format-3.0-but-debian-changes-patch for the archive. The extended description of this tag is:
This package declares source format 3.0 (quilt), but the Debian .debian.tar.gz file contains a debian-changes-VERSION patch, which represents direct changes to files outside of the debian directory. This often indicates accidental changes that weren't meant to be in the package or changes that were supposed to be separated out into a patch.
If this is intentional, you may wish to consider adding single-debian-patch to debian/source/options, and/or a patch header to debian/source/patch-header explaining why this is done.
This tag has not been emitted in any package tested by Lintian.
