Something like that (please remember that it is still in vague beginnings
of an idea stage:

  OUT_OBJECT(
     OUT_FIELD("mode",   OUT_MODE, tree.mode), SP,
     OUT_FIELD("type",   "%s", tree.object.type), SP,
     OUT_FIELD("object", OUT_SHA1, tree.object.sha1), TAB,
     OUT_FIELD("file", OUT_FILE(sep), tree.filename), 
     sep
  );
