format

[tkunze@mvax.kgw.tu-berlin.de (Tobias Kunze)]

i have a problem with format that is well beyond my scope (*print-pretty* 
is set to t):

  ? (format t "~@[~(~a~)~]" '(+ 1 2))
  (+ 1 2)                               ; this is fine (output is one line)
  NIL


now i add a ~& directive (the actual control string goes on beyond that)
and output is (and keeps being after that ~&) somewhat 'overprettyprinted':

  ? (format t "~@[~(~a~)~]~&" '(+ 1 2))
  (+ 1                                  ; arghh...
     2)
  NIL

Is this a bug in mcl? as far as my understanding goes, this should not
happen.

Thanks, Tobias Kunze
