Overhaul the description of `jump`/`goto`/`return`. `jump` only explains what the statement causes from the point of view of the new chain (that is: not, how the returning works), which includes that an implicit `return` is issued at the end of the chain. `goto` is explained in reference to `jump`. `return` describes abstractly how the return position is determined and what happens if there’s no position to return to (but not for example where an implicit `return` is issued). List and explain verdict-like statements like `reject` which internally imply `accept` or `drop`. Further explain that with respect to evaluation these behave like their respectively implied verdicts.
