This is particularly important for repositories where the worktree would become too large to be useful. This is even more important when using partial clone as well, since we want to avoid downloading the missing blobs for files that should not be written to the new worktree. The only way to create such a worktree without this intermediate step of expanding the full worktree is to copy the sparse-checkout patterns and config settings during 'git worktree add'. Each worktree has its own sparse-checkout patterns, and the default behavior when the sparse-checkout file is missing is to include all paths at HEAD. Thus, we need to have patterns from somewhere, they might as well be the current worktree's patterns. These are then modified independently in the future. In addition to the sparse-checkout file, copy the worktree config file if worktree config is enabled and the file exists. This will copy over any important settings to ensure the new worktree behaves the same as the current one. The only exception we must continue to make is that core.bare and core.worktree should become unset in the worktree's config file.
