 If the `--keep-index` option is used, all changes already added to the

++
+With `--patch`, you can interactively select hunks from in the diff
+between HEAD and the working tree to be stashed.  The stash entry is
+constructed such that its index state is the same as the index state
+of your repository, and its worktree contains only the changes you
+selected interactively.  The selected changes are then rolled back
+from your worktree.
++
+The `--patch` option implies `--keep-index`.  You can use
+`--no-keep-index` to override this.
