Starting with 1.9.0, we are merging the upstream tags as upstream,
instead of using the tarball that doesn’t ship tests.

# Example to import upstream 1.9.4 version
version=1.9.4
# We still use the upstream branch to drop the .gitattributes file from upstream
gbp import-ref --upstream-tag=%\(version%~%-\)s -u$version --debian-branch=upstream
gbp import-ref --upstream-tree=BRANCH -u$version
