In T7643, we changed how object field diffs are rendered. This improved most diffs, like wiki page edits and task description changes.

However, a small number of fields really are better off as code diffs. These include:

• Paste content (except maybe for pastes which contain prose, like ".txt", ".remarkup", etc).
• Config changes (at least, for JSON config).
• Maybe Almanac properties?

The prose diffs are normally fine in these cases, but restoring them to code diffs would be an improvement.
