I won't make an svn branch; they take too much maintenance.

Once you have a candidate for wider testing (i.e. something that works
as far as everyone knows in 4.9.x, and makes no changes to compiles in
4.6.3) I'll put it into R-devel.

To make sure these changes don't get lost, personally I'd use svn patch
to create a patch against current R-devel, and update that every now and
then as R-devel is revised.  You github users may find it easier to do
essentially the same thing on the github mirror.
