+test_description='git ls-tree test.
+
+This test runs git ls-tree with the following in a tree.
+
+    path0       - a file
+    path1	- a symlink
+    path2/foo   - a file in a directory
+    path2/bazbo - a symlink in a directory
+    path2/baz/b - a file in a directory in a directory
+
+The new path restriction code should do the right thing for path2 and
+path2/baz.  Also path0/ should snow nothing.
