Re: [PATCH v2 1/9] t7300: skip untracked dirs containing ignored files

> If git sees a directory which contains only untracked and ignored
> files, clean -d should not remove that directory. It was recently
> discovered that this is *not* true of git clean -d, and it's possible
> that this has never worked correctly; this test and its accompanying
> patch series aims to fix that.
