Right, I actually did have the same thought while writing it. And ended
up following that line of reasoning (since it's just a placeholder, it
doesn't matter).  But I'm not opposed to putting in the names.

Squashable patch is below; it goes on 34c829621e (diff: avoid generating
unused hunk header lines, 2018-11-02).

Junio, let me know if you'd prefer a re-send of the series, but it
doesn't look necessary otherwise (so far).
