It would be very expensive to implement C using that packed format for
character strings.  Some C implementations on other word addressed
machines decided to make char one word; on others arithmetic was needed
to convert between word and "char" pointers.  It's notable that,
programmer assumptions aside, word addressed machines are probably more
awkward for C the bit-addressed ones.
