Because there could be conflicts with no content differences (e.g. a modify/delete conflict resolved in favor of taking the modified file as-is), that commit also modified the diff_queue_is_empty() and diff_flush_patch() logic to ensure these headers were included even if there was no associated content diff. However, the added logic was a bit inconsistent between these two functions. diff_queue_is_empty() overlooked the fact that the additional headers strmap could be non-NULL and empty, which would cause it to display commits that should have been filtered out. Fix the diff_queue_is_empty() logic to also account for additional_path_headers being empty.
