apply: demonstrate a problem applying svn diffs

Subversion generates diffs that contain funny ---/+++ lines containing
more than just the file names. Example:

--- a/trunk/README	(revision 4711)
+++ /dev/null	(nonexistent)

Let's add a test case demonstrating that apply cannot handle the
/dev/null line (although it can handle the trunk/README line just fine).
