One usecase for edit index

After a big change in foo.c in the worktree, you find a typo in foo.c.
You want to fix the typo first before commit the big change. But the
change is so big that you can't just fix the typo in worktree foo.c
and then use "add -p" to pick the typo fix first.

So you can

git stash
fix typo and commit
git stash apply and resolve the conflict

With 'add --edit=patch', you can
git add --edit=patch foo.c

an editor is fired up with the foo.c in index and worktree open side
by side. And you can fix the typo in both index and worktree file.
When exiting the editor, the index file is modified, and no conflict
to resolve.
