Re: [PATCH 1/1] diff-lib: use worktree mode in diffs from i-t-a entries

> When creating "new file" diffs against i-t-a index entries, diff-lib
> erroneously used the mode of the cache entry rather than the mode of the
> file in the worktree. This changes run_diff_files() to correctly use the
> mode of the worktree file in this case.
