When reporting that an unvisited member remains at the end of an input visit for a struct, we were using g_hash_table_find() coupled with a callback function that always returns true, to locate an arbitrary member of the hash table. But if all we need is an arbitrary entry, we can get that from a single-use iterator, without needing a tautological callback function.
