Make git ls-files omit deleted files

Hello, I'm trying to copy my current git worktree to a new directory, while including all modified and untracked files, but excluding any ignored files. I essentially want a copy of the tree assuming someone ran `git add --all && git commit` and cloned that commit into a different directory.

I got pretty close with the following command:

    $ git ls-files --cached --modified --others --exclude-standard
--deduplicate | xargs cp --parents --no-dereference
--target-directory=/tmp/clone/

The problem is that if I have an unstaged delete, `ls-files` will print it out as a modification and `cp` will print an error saying that it failed to copy the non-existing file.

The man page states this behavior:

Is there another way to achieve what I'm doing that's not too expensive? If not, could a `--no-deleted-as-modified` flag be added?

Thanks, Raul
