(→Linking to a diff: it makes more sense to list the 'better' method first, followed by the less desired method.)
When moving or copying a piece of text within a page or from another page, and also making other edits in the same revision, the diff display can become cluttered and confusing. Instead, a diff can be kept clearer (simpler), by first using a separate edit to move, or split, text paragraphs, then after saving, in the next edit revisions, add or change text within the split paragraphs. If paragraphs are both split and reworded in the same revision, then the new words cannot be highlighted as different from the prior revision.
A diff shows differences per line, so it relies on matching [[newline]]s. Some editors find that having additional line breaks to break up the text improves the diff function. Otherwise, those large, massive globs of text are difficult to compare. Keep sentences limited in length, such as with
