test_description='grep in sparse checkout
This test creates a repo with the following structure:
.
|-- a
|-- b
|-- dir
| `-- c
|-- sub
| |-- A
| | `-- a
| `-- B
| `-- b
`-- sub2
`-- a
Where the outer repository has non-cone mode sparsity patterns, sub is a
submodule with cone mode sparsity patterns and sub2 is a submodule that is
excluded by the superproject sparsity patterns. The resulting sparse checkout
should leave the following structure in the working tree:
.
|-- a
|-- sub
| `-- B
| `-- b
`-- sub2
`-- a
But note that sub2 should have the SKIP_WORKTREE bit set.
