rrule generator skipping window during exit of DST

I would expect it to work this way, because rrule is working with the standard datetime semantics that operates on the naïve portion of the datetime, and this behavior is consistent with what you would expect based on how datetime.datetime works (which, admittedly, is not the way most people expect it to work).

That said, rrule is intended to be an implementation of the RRULE / RRULESET types from the relevant iCalendar RFCs, so if the spec says that the behavior of RRULE in the presence of DSTs should be to emit the duplicated hour twice, we should change it (though I think doing so might be quite complicated in a general way).
