[O] pandoc export does not honour org-export-with-sub-superscripts?

[Bingo UV]

Hi,
   With emacs 24.5.1, melpa ox-pandoc from 20150706.1809 and
   org-plus-contrib-20151109, I have set
   org-export-with-sub-superscripts to {}. It has the correct behaviour
   in html export, or latex export. But with pandoc, A_B and A_{B} both
   get exported with B as subscript.

Are there special settings in ox-pandoc for this?

thanks
