The 2eac2a4c (ls-files -k: a directory only can be killed if the
index has a non-directory, 2013-08-15) is NOT a correctness fix.

It is an optimization to avoid scanning directories that are known
not to be killed when "ls-files -k" is asked to list killed
paths. The original code without the patch is correct already; it
just is too inefficient because it scans all the directories.  It is
not surprising if the test added by 3c568751 (t3010: update to
demonstrate "ls-files -k" optimization pitfalls, 2013-08-15) passes
without 2eac2a4c.

As its log message explains, 3c568751 (t3010: update to demonstrate
"ls-files -k" optimization pitfalls, 2013-08-15) is to catch a case
where an earlier "something like this" patch (which is the draft for
2eac2a4c) posted to the list would have broken.  That draft patch
was correct only for the case where the top-level directory is
killed, but was broken when a subdirectory (e.g. pathx/ju) is
