test_description='git-checkout-cache test.

This test registers the following filesystem structure in the
cache:

    path0       - a file
    path1/file1 - a file in a directory

And then tries to checkout in a work tree that has the following:

    path0/file0 - a file in a directory
    path1       - a file

The git-checkout-cache command should fail when attempting to checkout
path0, finding it is occupied by a directory, and path1/file1, finding
path1 is occupied by a non-directory.  With "-f" flag, it should remove
the conflicting paths and succeed.
