This seems like an early optimization. The time needed to touch an
empty file seems like nothing compared to creating a new process
and running diff. We might also just create an empty foo.c in the
pristine dir when `svn add foo.c` is run. It seems like getting the feature
implemented and tested is more important than this minor impl detail.
