By my reading ofhttps://github.com/bbatsov/clojure-style-guide#vertically-align-fn-args, we should indentif like so:

(if condition    (f1)    (f2))

...but that's contradicted by other examples in the guide, which use the common two-space indentation forif. Technically the rule might not coverif since it's a special form and not a macro, but there's alsoif-let andif-some and it would be very weird IMO to indent them differently. It would be good to mention this explicitly, even if just to call outif and friends as exceptions.

(I searched for existing issues covering this, but the closest I found was#87.)
