Subject: [PATCH] * lisp/ob-eval.el: Display error fix

* lisp/ob-eval.el: (org-babel-eval-error-notify): Display standard
error only if command exits non zero.

The problem is that sql connections might give warnings.
Now the information is available in the *Org-Babel Error* buffer
without displaying.
If you need always display toggle org-babel-eval-error-display-notify.
