Hello
Attached is a hack based on the code that indents LOOP (in contrib/slime-indentation.el) to indent IF*. I'm aware that few people hack on code with IF* but to them it's quite useful.
You need to load the slime-indentation contrib and this file.
It does this:
(if* (eq t nil) then () () elseif (dsf) thenret x else (balbkj) (sdf))
Yes, that was the spec and the user doc.
Cheers, Gabor
