`last_stop` not set

Running this sql:

select * from stop_times where last_stop != 0;

It appears that no stop_times have a last_stop of 1. I think this is because of the code in the GtfsToSql exporter:

https://github.com/TransitFeeds/GtfsToSql/blob/4236561215a8f739b4170e2ecb7019867a60bfde/src/com/transitfeeds/gtfs/GtfsOptimizer.java#L49

Perhaps it' not getting run? Setting this field will be helpful because if the closest stop is the last stop on a trip, we know not to show that direction as an option.

I figured this out the other day, you have to pass in -o to get the optimizer to run:
