Actually it looks like I was wrong about using add-function with
choose-completion-string-functions, it's just a plain list you stick
functions into. I think it has to be an error not to declare it
buffer-local... I've worked around this with `make-local-variable', but
I'm halfway sure this should be a defvar-local...?
