(ice-9 optargs) lambda* and define* #:rest broken

(define foo (lambda* (#:key (atts '()) #:rest rest) (format #t "Atts:
~S; Rest: ~S~%" atts rest)))

(foo #:atts '(1 2 3) 'foo 'bar)
] Atts: (1 2 3); Rest: (#:atts (1 2 3) foo bar)

The same occurs with define*, the keyword arguments are not removed from
the rest list. This is broken in 1.6.x and CVS HEAD.

This is the behavior that Common Lisp specifies, so we will have to
argue whether it really is a bug of Guile to behave this way.

In fact, the above is probably a bug, but a different from yours: the
'foo 'bar arguments should raise an error since they are not a
keyword-value pair.
