No problem at all, thanks for following up!

If a user manually modifies a SKIP_WORKTREE file, SKIP_WORKTREE will be
removed from the file and the index expanded automatically [1]. If that
mechanism is working properly, there would be no need to manually check the
pathspec and expand the index.
Have you tried removing the 'pathspec_needs_expanded_index()' and running
the tests? If so, is 'diff-files' producing incorrect results?
