I see. This certainly makes sense. I'll inform the maintainer of the macro
:-).

I suppose it wouldn't be too difficult to arrange, but ... why? I really
can't see a situation in the current slime where that would be useful. I
put the code to remove those parts of the arglist as high up as I could, so
that their effect would be localized to 1) the macro indentation function,
and 2) "Print the list ARGLIST for display in the echo area." Any other
code is unaffected by these changes.
