This is what we use for many other patterns in this file :)

But the way I test it is by trying with `.gitignore` (GitHub claims that they use the same format).

So I modify a file (or create a new path), check that it shows up in `git status`, then I add the pattern to `.gitignore` and check that it does not show up in `git status` output anymore!
