"treat <destination> as a directory exists in the working tree" is a bit
akward, and the rest of the sentence struggles with that. Starting with
"If yes," we could rewrite as follows:
If <destination> is such a sparse directory, then we should modify the
index the same way as we would if this were a non-sparse directory. We
must be careful to ensure that the <destination> is marked with
SKIP_WORKTREE_DIR.
(Note that I don't equate this as doing the same thing, just operating on
the index.)

I think this part doesn't need to be there, but I don't feel strongly
about it.

Hm. I find it interesting how this works even if the directory is _not_
present in the index. Is there a test that checks this kind of setup?
git init &&
>file &&
git add file &&
git commit -m init &&
mkdir dir &&
git mv file dir/
Locally, this indeed works with the following 'git status' detail:
renamed: file -> dir/file

Looks like we are assigning dst_mode here, but not using it. I wonder if
you'll get a compiler error if you build this patch with DEVELOPER=1.
You can test all of the commits in your series using this command:
git rebase -x "make -j12 DEVELOPER=1" <base>
> + if (dst_w_slash != dest_path[0])

Good that you are freeing this here. You might also want to set it to NULL
just in case.
