Why should (make-string 1 ?a) produce a unibyte string?  Why can't it
produce a multibyte string instead?

More generally, how about if we make sure _all_ string-producing
primitives return multibyte strings, and unibyte strings can only be
produced by a few specialized ones which have "-unibyte-" in their
name?
