In #3421 we created a new folder but it didn't get picked up by the publish script.
```
Untracked files:
(use "git add <file>..." to include in what will be committed)
js/
```
The reason is that `git diff-index --quiet HEAD --` returns 0 for untracked files. But, if we add before, it returns 1.
It still returns 0 if we add but there's nothing changed
