I only get a #+results line if I do C-c C-c on the block. I'm
primarily tweaking other stuff and just using C-c C-e p to export to
LaTeX, which produces no #+results section and thus does not allow me
to use a center environment around that bit. I suppose I can manually
add them, but if I re-evaluate babel doesn't recognize it as the
#+results section anymore and I wind up with this after the second

#+RESULTS: foo

#+LATEX: \begin{center}
#+RESULTS: foo
#+LATEX: \end{center}

I still may consider it as an interim solution. I'm surprised there's
no option to center resultant plots!
