Another question: is it customary for major modes to invoke
buffer-face-mode? I was a bit confused when I first saw "BufFace" in the
mode-line, as I had not explicitly invoked the minor mode. My
understanding was that this was primarily intended as a minor mode for
user-level modifications, not for major modes to rely on (but I may very
well be mistaken).
