Replaces a test whose name promised more than its body checked: it
looped the grammars asserting Pattern != nil, which regexp.MustCompile
already guarantees at init. Asserting the grammars pass IsAgendaQuestion
would be true by construction, since the first arm is that same loop.
A hand-written example per grammar name catches what neither does: a
grammar edited until it no longer matches the case its comment gives,
and a new grammar nobody wrote an example for.
