cider-eval-defun-at-point doesn't work properly if there is a space in the beginning of namespace declaration

[mattiuusitalo]

Expected behavior

Evaling the defun works normally

Actual behavior

I get compile errors about undeclared vars, declared vars end up in "user" namespace

Steps to reproduce the problem

Create a namespace with space in the namespace declaration, like this:

 (ns foo) ; space as the first character

(defn bar [] 1)

eval defun at point for the function "bar". I can instantly see the foo was declared in "user" namespace. I expected it to end up in "foo" namespace. If I require stuff in the namespace declarations, I can't refer to the declarations because I get compile errors

This is actually because of clojure-mode, not CIDER. clojure-find-ns returns nil in this case.

Yep. Please, report the issue there.
