Diff containing new empty file

[Tristan Hill]

Should diff be able to indicate a new empty file?  Or is it a know
unsupported case?

e.g.

$ find 
.
./old
./new
./new/__init__.py
./new/test.py

where new/__init__.py is an empty file, diff produces;

$ diff -Naur old new
diff -Naur old/test.py new/test.py
--- old/test.py 1970-01-01 01:00:00.000000000 +0100
+++ new/test.py 2006-11-07 21:41:43.897567993 +0000
@@ -0,0 +1 @@
+test = 1
$ diff --version
diff (GNU diffutils) 2.8.1
