test_description='git ls-files -k and -m flags test.

This test prepares the following in the cache:

    path0       - a file
    path1       - a symlink
    path2/file2 - a file in a directory
    path3/file3 - a file in a directory
    pathx/ju    - a file in a directory
    submod1/	- a submodule
    submod2/	- another submodule

and the following on the filesystem:

    path0/file0 - a file in a directory
    path1/file1 - a file in a directory
    path2       - a file
    path3       - a symlink
    path4	- a file
    path5	- a symlink
    path6/file6 - a file in a directory
    pathx/ju/nk - a file in a directory to be killed
    submod1/	- a submodule (modified from the cache)
    submod2/	- a submodule (matches the cache)

git ls-files -k should report that existing filesystem objects
path0/*, path1/*, path2 and path3 to be killed.

Also for modification test, the cache and working tree have:

    path7       - an empty file, modified to a non-empty file.
    path8       - a non-empty file, modified to an empty file.
    path9	- an empty file, cache dirtied.
    path10	- a non-empty file, cache dirtied.

We should report path0, path1, path2/file2, path3/file3, path7 and path8
modified without reporting path9 and path10.  submod1 is also modified.
