Merge branch 'en/sparse-checkout-fixes'
Further polishing of "git sparse-checkout".
* en/sparse-checkout-fixes:
sparse-checkout: reject arguments in cone-mode that look like patterns
sparse-checkout: error or warn when given individual files
sparse-checkout: pay attention to prefix for {set, add}
sparse-checkout: correctly set non-cone mode when expected
sparse-checkout: correct reapply's handling of options
