I'm not so sure the examples are right, note that CLtL2 does say:

  "The : modifier causes commas to be printed between groups of three digits."

and in dpANS I don't see this particular example; the similiar
examples all use the `:'.

CLISP does obey the `:':

  > (format nil "~,,' ,4:B" #xface)
  "1111 1010 1100 1110"

I think if the fourth parameter implied a `:', it would be
a nuisance if format strings were being generated by a program.
