The healthy workflow is: notice formatting discrepancies -> reformat -> reopen the diff, now containing only intentional, substantial changes. Of course the edited source files should have been reformatted automatically, on save or on build, before someone opens a diff: this should never happen except as a symptom of inadequate reformatting (e.g. I decide to adopt redundant commas at the end of comma-separated lists) or abnormal operations (e.g. non-reformatted code was accidentally committed to version control).
