Well played. The %Y prompt can be a separate patch.

New patch. Highlights:
- rebased to master as of ten minutes ago
- Interactive barking on branching state changes, commands typed while in
inactive state
- Help text. New block in help text called "Conditionals"
- SendQuery calls in mainloop.c are all encapsulated in send_query() to
ensure the same if-active and if-interactive logic is used
- Exactly one perl TAP test, testing ON_ERROR_STOP. I predict more will be
needed, but I'm not sure what coverage is desired
- I also predict that my TAP test style is pathetic
- regression tests now have comments to explain purpose
