From: Derrick Stolee <redacted> The diff_populate_filespec() method is used to describe the diff after a merge operation is complete, especially when a conflict appears. In order to avoid expanding a sparse index, the reuse_worktree_file() needs to be adapted to ignore files that are outside of the sparse-checkout cone. The file names and OIDs used for this check come from the merged tree in the case of the ORT strategy, not the index, hence the ability to look into these paths without having already expanded the index.
