test_description='git ls-files test (--others should pick up symlinks).

This test runs git ls-files --others with the following on the
filesystem.

    path0       - a file
    path1	- a symlink
    path2/file2 - a file in a directory
    path3-junk  - a file to confuse things
    path3/file3 - a file in a directory
    path4       - an empty directory
