Was it intentional that the version of cl-indent.el in SLIME changed the indentation for the LOOP macro? In particular cl-indent in SLIME now does this indentation:
(loop for x in l for y for = (foo x) do (mumble x y))
whereas cl-indent in EMACS does this indentation:
(loop for x in l for y for = (foo x) do (mumble x y))
I much prefer the EMACS indentation.
