Sigh. As danpb pointed out when I sent this before, I had copy/pasted
a "since" clause (and taken the time to make sure I could still do a
build) but hadn't bothered to replace the version number itself in the
bit that I pasted :-/

(this is why I don't allow the "trivial" rule for pushing patches to
apply to myself)
