Do you mean the `diff-refresh-hunk' command? I does indeed ignore
`diff-switches', but that's because it tries to keep the style of the
diff consistent:
(defun diff-refresh-hunk (&optional ignore-whitespace)
"Re-diff the current hunk."
(interactive)
(let* ((char-offset (- (point) (diff-beginning-of-hunk t)))
(opt-type (pcase (char-after)
(?@ "-u")
(?* "-c")))
Which I think sounds like the correct design. What's the use case you
have for diff-switches where you'd want this command to heed diff-switches?
