Ah.  That's a problem.  Older versions of Emacs would indeed foul up on
seeing that in .dir-locals.el.

We could really do with being able to write (if (fboundp ...) ...) in a
.dir-locals.el.  I don't think we've any way of doing this at the moment.

Maybe I could amend the amendment for /* */ so that it would need only to
set a variable in .dir-locals.el rather than calling a function.  Would
that work better?
