ob: Fix block evaluation in a narrowed buffer
* lisp/ob.el (org-babel-where-is-src-block-result): Insert new results keyword in current narrowed part of buffer, if necessary. Small refactoring. (org-babel-insert-result): Do not widen buffer when new results have to be inserted. Therefore, results inserted after the last block of a narrowed buffer still belong to the narrowed part of the buffer. * testing/lisp/test-ob.el: Add tests. * testing/lisp/test-ob-exp.el: Move test to test-ob.el
