[CLJ-1185] `reductions should respect `reduced Created: 16/Mar/13  Updated: 14/Apr/14

This returns 16:

(reduce (fn [acc x]
          (let [x' (* x x)]
            (if (> x' 10)
              (reduced x')

But replacing `reduce with `reductions will never terminate:

(reductions (fn [acc x]
              (let [x' (* x x)]
                (if (> x' 10)
                  (reduced x')

This is because `reductions ignores 'clojure.lang.Reduced, it never tests for `reduced?

I know that I only just discovered the `reduced, function, but `reductions is a big part of my debugging process, so it's unfortunate that they don't work together.

It isn't guaranteed to help, but it can't hurt to vote on the ticket, and encourage anyone else you know who wants this fixed to vote on it.
