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.
