Improvement identified in #2790. Add a prefix to the diff-id when it is used multiple times in different "how to fix it in XYZ" sections to avoid ambiguity and pedantically follow the spec: > A single and unique diff-id should be used only once for each type of code example as shown in the description of a rule. Obvious typos around `diff-type` were fixed.

If octal notation is required, use the standard syntax: a leading zero followed by a lowercase or uppercase Latin letter "O" (`0o` or `0O`).
