Everything work as expected expect for cpR

  According to the clojure-doc tutorial, cpR should (require
  :reload-all) the current namespace. Well... not in my machine.
  If I use :Reload! instead, it works, so I wonder if cpR worked in
  previous vim-fireplace versions, or there's something I'm missing.
