That's strange: it's "courier" in 25.1, but the release branch says
fixed-pitch-serif, and the change was in May, so should have been in
the released Emacs 25.1.

Nicolas, can you shed some light on this?

It chooses the first font that satisfies the request.

That's what we do, except that this somehow didn't get into Emacs
25.1.
