Junio C Hamano 3c56875176 t3010: update to demonstrate "ls-files -k" optimization pitfalls
An earlier draft of the previous step used cache_name_exists() to
check the directory we were looking at, which missed the second case
described in its log message.  Demonstrate why it is not sufficient.

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
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
git ls-files -k should report that existing filesystem
objects except path4, path5 and path6/file6 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.
