Should reset range after non-undefined themes.
Found a minor snag. Need to prevent rule for approach notes from activating on octave reset.
Added some insight. Will *not* prevent the problem with approach notes in general, though.
This was meant to solve the problem with approach notes, but reintroduces problem with infinite backtracking.
Was using a wrong variable. This should solve both outstanding issues. Now to do a gazillion test runs.
