[ESS] Is this useful for discriminating Sweave vs knitr docs?

Thanks Martin, Rainer.

I'm a bit wary of having two syntaxes around (think about the poor end
user... what if two conflicting values are provided?).

Any of the Rstudio team on here and wish to comment?  I'm all for trying
to ensure we keep our conventions together a bit more closely.
(Sectioning comments is another that springs to mind.)
