Note about hidden option
Syntax keywords update

* Replace test->, test->> with cond->, cond->>

* Remove sequence functions from clojureRepeat, keeping only imperative
  looping keywords. Now the Repeat group actually conveys useful
  information

* We are going to re-add dictionary completions for clojure.core and the
  special forms, so we add that logic here.

* lein-exec will never use bleeding edge Clojure, so don't even bother
  with it.
