The nice thing with the (not so nice) function I ended up with is that it 
would be fairly easy to use any other function, such as rmarkdown::render 
instead of knitr::pandoc. As for me, as I already use knitr (obviously) to 
knit, and pandoc is also installed on my system, it makes more sense to use 
what's available! Or maybe I'm missing the obvious: is there a strong 
argument in favor of rmarkdown::render instead of knitr::pandoc?

Mathieu.
