[O] Bug: Org-indent does not align headings with text when using non-monospaced fonts [8.3.1 (8.3.1-16-gf6aa53-elpa @ /Users/cube/.emacs.d/elpa/org-20150810/)]

[Jakub Szypulka]

Reproduction of bug: Open an org-file in org-mode with auto-indent turned on 
while using a non-monospaced font.
Expected result: The headings align with the text contents.
Actual result: The headings do not align with the text contents.

This has been originally filed two years ago:
http://article.gmane.org/gmane.emacs.orgmode/64775/match=indent+misalign

There is a proposed fix: replace the blankspace used to indent a line, defined 
in org-indent.el, with a star ('*').

Thanks in advance for fixing!
