[elpa] externals-release/org 89d13998bd 1/2: org-element-fixed-width-parser: Fix when :value is empty

[ELPA Syncer]

branch: externals-release/org
commit 89d13998bd6ad4144d383ede16ff71cfaae439b3
Author: Ihor Radchenko <yantar92@posteo.net>
Commit: Ihor Radchenko <yantar92@posteo.net>

    org-element-fixed-width-parser: Fix when :value is empty
    
    * lisp/org-element.el (org-element-fixed-width-interpreter): Interpret
    fixed-width element with :value "" as ":\n", not as empty string.
    * testing/lisp/test-org-element.el 
(test-org-element/fixed-width-interpreter):
    Fixed the test.
    
    The previous test, albeit intentionally asserting "" result, breaks
    reversibility of parse-interpret sequence.
