Running cljfmt with only `: insert-padding-lines?` enabled produces non-blank-line changes

$ cat .cljfmt 
{:max-blank-lines 3
 :single-import-break-width 1000
 :indentation? false
 :remove-surrounding-whitespace? false
 :remove-trailing-whitespace? false
 :insert-missing-whitespace? false
 :remove-consecutive-blank-lines? false
 :insert-padding-lines? true
 :rewrite-namespaces? false}
$ cat foo.clj
(ns foo)

(defn foo-two []
  nil)
$ cljfmt check foo.clj

+++ b/foo.clj
@@ -1,4 +1,6 @@

I would expect the diff to be:

Should probably dupe this into #9 I guess...
