Works as intended for me:

├── baz
│   ├── quux
│   │   ├── corge
│   │   │   └── wibble.txt
│   │   └── grault.txt
│   └── waldo.txt
└── foo
    ├── bar.txt
    └── garply.txt

$ git status -s -uall
?? baz/quux/corge/wibble.txt
?? baz/quux/grault.txt
?? foo/bar.txt

garply.txt and waldo.txt are ignore, but the rest is still tracked.

I'm on 2.7.2.
