        I believe (but am not sure) that the %r embedded format spec
        could not be implemented successfully on all computer
        architectures whereas varargs can.

That is true, if we define the operand of %r to be a char **.  But if
we define it to be a va_list (a type defined in <varargs.h>) we get
a portable interface, and upward compatibility from V7 on most
architectures.
