Yeah. That's worthy of a comment, I think (see below).

I don't think we will detect a case with just a missing name _or_ email,
but neither did the original.

Yes. Looks like the original leaked "buf" in the same way.

Rather than repeat the strbuf_release, I think we can introduce a goto,
like:

That should make it easier to handle the cases added later in the
series, too.
