From: Derrick Stolee <redacted>

When the --no-sparse-index option is supplied, the sparse-checkout
builtin should explicitly ask to expand a sparse index to a full one.
This is currently done implicitly due to the command_requires_full_index
protection, but that will be removed in an upcoming change.
