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

+In some cases, saving a stash could mean irretrievably removing some
+data - if a directory with untracked files replaces a tracked file of
+the same name, the new untracked files are not saved (except in case
+of `--include-untracked`) but the original tracked file shall be restored.
+By default, `stash save` will abort in such a case; `--force` will allow
+it to remove the untracked files.
