It's "Oops, the next one (refs.c: do not permit err == NULL) is broken,
and this is to patch it up in advance". :)

But it should apply on top, too.

There were a few other minor changes, and I think with them the series
should be ready for "next".  My "send and hope that more reviewers
appear" strategy didn't really work, so I'll send a reroll of the
series as-is in an hour or so.

Here's an interdiff as a preview.
