The issue here is that this file is "untracked", not just outside
of the sparse-checkout cone.

Instead, what about

	git mv folder2/a deep/new

since folder2/a is a tracked file, just not in the working tree
since it is outside the sparse-checkout cone.

(If it fails, then it should fail the same with and without the
sparse index, which is what "test_sparse_match" is for.)
