[O] [BUG] centering export of babel results

[Andreas Leha]

Hi all,

There is a bug in the newly introduced centering-instead-of-center
feature when it comes to babel results.

Here is the problem (already *unintentionally* centered):
#+begin_src R :exports results :colnames yes
  data.frame(a=1:2, b=3:4)
#+end_src

#+results:
| a | b |
|---+---|
| 1 | 3 |
| 2 | 4 |

This remains *unintentionally* centered.

Regards,
Andreas
