+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.
