Description

Pretty printing code using pprint with code-dispatch incorrectly prints a simple ns macro call.
The problem is that "nil" is added to the output after the namespace name.

user> (use 'clojure.pprint)
nil
user> (def code '(ns foo.bar))
#'user/code
user> (with-out-str (with-pprint-dispatch code-dispatch (pprint code)))
"(ns foo.barnil)\n"   ;; Expected: {{"(ns foo.bar)\n"}}

Cause: In clojure.pprint/pprint-ns-reference, reference is printed regardless, but may be nil.
Solution: Omit printing reference if nil.
Patch: simple-ns-pprint-fix.patch
