Merge branch 'nd/fix-sparse-checkout'
* nd/fix-sparse-checkout: unpack-trees: mark new entries skip-worktree appropriately unpack-trees: do not check for conflict entries too early unpack-trees: let read-tree -u remove index entries outside sparse area unpack-trees: only clear CE_UPDATE|CE_REMOVE when skip-worktree is always set t1011 (sparse checkout): style nitpicks
