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 mulitple directories which have matching file
entries.  Also test odd filename and missing entries handling.
