[slime-devel] indentation of LOOP

If there's not a major outcry, I'll make `slime-setup' do the following (setq lisp-simple-loop-indentation 1 lisp-loop-keyword-indentation 6 lisp-loop-forms-indentation 6) so LOOP gets indented like (loop for x ... for y ... collect (cons x y)) instead of (loop for x ... for y ... collect (cons x y)) -T.
