If the `--keep-index` option is used, all changes already added to the
index are left intact.
++
+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
