Well, it has only existed for about a month, but the customizations its 
selects are often much older and were documented as being used by CRAN.

It switches on a customization that has been documented for years ....

You are strongly recommended to run this *on the tarball to be 
submitted*.  If you have .svn directories in that tarball, then you do 
(or CRAN will) have a problem.  R CMD build does omit such directories, 
and you can of course use .Rbuildignore to ignore other things.

Or if you update to subversion 1.7.x the problem will evaporate, as that 
only stores .svn directories at the top level, in my case ~/R/svn/Rpkgs, 
above all the individual packages.
