Subject: [PATCH] initialize org-babel-tangle-lang-exts to nil

* lisp/ob-C.el (org-babel-tangle-lang-exts): init to nil
* lisp/ob-awk.el (org-babel-tangle-lang-exts): init to nil
* lisp/ob-clojure.el (org-babel-tangle-lang-exts): init to nil
* lisp/ob-fortran.el (org-babel-tangle-lang-exts): init to nil
* lisp/ob-groovy.el (org-babel-tangle-lang-exts): init to nil

* lisp/ob-ruby.el (org-babel-tangle-lang-exts): init to nil
* lisp/ob-sed.el (org-babel-tangle-lang-exts): init to nil

org-bable-tangle-lang-exts should be initialized to nil and not as a
void variable, if it is not already initialized then this will cause a
void-variable error immediately when it is used in add-to-list

this corrects the original addition in
4a0e5cf88f684db775ccf43dc5edc2e8754a2d92 as well as other files that
followed the pattern
