Description
Demonstrate and explain diff labels that show the difference between the steps of a proof state.
This will need some technical work:
- Verso support for rendering these labels in proof states
- A testable way to show which parts are which, so that the text stays in sync with the implementation (along the lines of the current testable tactic examples)

Research direction
Start by locating the Verso support for rendering proof-state labels and reviewing the current testable tactic examples. Determine how to demonstrate which parts of a proof state correspond to each diff label. Done means the reference manual explains the labels and includes a testable example that stays in sync with the implementation.
