Again, this is pure code motion, and is totally stand alone. The prior patch is a functional change that could have an impact and has no relation at all to this code motion. It is best practice to keep those distinct things.

I keep my position here. For me it is easier to backtrack later on what was made and quicker to backport. Probably not the biggest concern for you either so no much harm done... > Jason /Jarkko ------------------------------------------------------------------------------ Go from Idea to Many App Stores Faster with Intel(R) XDK Give your users amazing mobile app experiences with Intel(R) XDK.
