If the use of floating point formats still causes arguments to be
consumed as usual, then I am OK with this.  Even better if something
vaguely sensible is printed, like treating all floating point formats as
if they were %a.  (Oh, we don't support %a.  It's supposed to print in

If the use of floating point formats causes bad things to happen, or if
"%f" behaves like "%%f" without consuming any arguments, then I don't
like it.
