[PATCH 3/3] Add git-ls-files -k.
When checkout-cache attempts to check out a non-directory where a directory exists on the work tree, or to check out a file under directory D when path D is a non-directory on the work tree, the attempt fails. Before running checkout-cache, the user can run git-ls-files with the -k (killed) option to get a list of such paths. The tagged output format uses "K" to denote them. This is useful for Porcelain layer to be careful when dealing with the recently corrected behaviour of checkout-cache.
