Bug#828167: pandoc: in RST to HTML, no URI duplication in relative links when reference omitted

[John MacFarlane]

Thanks for your very helpful report. I have fixed this bug (commit
d283f9c864fc4a9ed8ffa4711dda9014b886149b).  The fix is
available now in the dev version and will be in the next
release.
