This is now hopefully fixed

Done. I added the script inst/codebloat/codebloat.R that one can call 
from the root of Rcpp source tree like this :

Rscript inst/codebloat/codebloat.R 20

and updated the number to 20 (is this enough ?)

not sure this is the best way to do it, so I'm open to suggestions, etc ...

I've tagged this as Rcpp version 0.7.9.3.
