+Check that amend properly preserve rename from directory rename (issue-4516)
+
+If a parent of the merge renames a full directory, any files added to the old
+directory in the other parent will be renamed to the new directory. For some
+reason, the rename metadata was when amending such merge. This test ensure we
+do not regress. We have a dedicated repo because it needs a setup with renamed
