I've cc'd him.  He told me that this is a toplevel bug; the scripts
generated by autoconf are careful to preserve quotes, but of course our
toplevel stuff is not (yet) autoconfiscated.  I'll hold off on touching
anything in the v3 configury until after he gets a chance to look at the
situation (and your patch).
