Rename with Parinfer eliminates whitespace unnecessarily

[jeff303]

Not sure if exactly related to #2106. With Parinfer enabled, place cursor over the first c below, and initiate Rename refactor.

(let [a     1
      b-sym {:x 1}
      c     "foo"]
  [a b-sym c])

Without typing anything, immediately the whitespace is rewritten (so map vals do not line up anymore):

(let [a 1
      b-sym {:x 1}
      c "foo"]
  [a b-sym c])

I could understand this happening if renaming b-sym (since its length currently influences the spacing of all the vals), but just changing c to c-new (for example) shouldn't make this happen. The workaround is to temporarily disable structural editing when performing a Rename.
