crml (move to let) does not indent properly

This is sort of similar to #21, though I'm not sure if it's technically related or not.

If I have this form:

(let [advertiser (-> advertiser
                       (unparse-custom-fields :rtbcustomfields))]
    (if (zero? id)
      (api-client/create-advertiser! (api-key) advertiser)
      (api-client/update-advertiser! (api-key) advertiser)))

And I move my cursor to the (zero? id) form and do crml, naming the binding id-zero?, this is the result:

(let [advertiser (-> advertiser
                   (unparse-custom-fields :rtbcustomfields))
    id-zero? (zero? id)]
(if id-zero?
  (api-client/create-advertiser! (api-key) advertiser)
  (api-client/update-advertiser! (api-key) advertiser)))

(This is with parinfer disabled. With parinfer enabled, it's worse because parinfer rearranges my parens based on the indentation.)
