[O] Comments in @example in org.texi

[Rasmus]

Hi,

In org.texi, sometimes examples have comments with (·) and sometimes with
@r{·}.  E.g.

   @example
   #+TOC: headlines 1 local  (insert local TOC, with direct children only)
   @end example

And

   @example
   #+INCLUDE: "~/.emacs" :lines "5-10"   @r{Include lines 5 to 10, 10 excluded}
   @end example

Is there any logic behind when @r{·} and when (·) is used?  Or should we
try to make it more coherent?

Thanks,
Rasmus
