Revert "git stash: avoid data loss when "git stash save" kills a dire…

…ctory"

This reverts commit a736531, as it
has been reported that "ls-files --killed" is too time-consuming in
a deep directory with too many untracked crufts (e.g. $HOME/.git
tracking only a few files).

We'd need to revisit it later but "ls-files --killed" needs to be
optimized before it happens.

 The `--patch` option implies `--keep-index`.  You can use
 `--no-keep-index` to override this.
