[PATCH v2 0/2] Safety for "stash save"

The second patch is the real thing, but "ls-files --killed" needed to be taught about submodules to avoid breaking "stash save" in a repository with submodules, as the new safety uses it to detect what will need to be killed (i.e. file D/F in the working tree getting removed because we need to check out D as a file, or file D in the working tree getting removed because we need to check out D/F as a file) when reverting to the state in HEAD.

Junio C Hamano (1):
  treat_directory(): do not declare submodules to be untracked

Petr Baudis (1):
  git stash: avoid data loss when "git stash save" kills a directory
