+test_description='git ls-tree directory and filenames handling.
+
+This test runs git ls-tree with the following in a tree.
+
+    1.txt              - a file
+    2.txt              - a file
+    path0/a/b/c/1.txt  - a file in a directory
+    path1/b/c/1.txt    - a file in a directory
+    path2/1.txt        - a file in a directory
+    path3/1.txt        - a file in a directory
+    path3/2.txt        - a file in a directory
+
+Test the handling of multiple directories which have matching file
+entries.  Also test odd filename and missing entries handling.
