Looking good.

First of all, agreed about the "not that big a deal" part. Just a random
thought: You could do the opposite of what Elijah sometimes does by
first adding a "MAYBE_UNUSED" function, then actually using it. You'd
add "MAYBE_UNUSED" here, then the next commit would drop the whole
thing. It could be worth it if you're removing many many lines so that
the "actual" change gets lost in the noise. But this patch isn't near
any such threshold, IMHO (if there even is such a "threshold").

Handling NULL. Nice. :)
