de-count schistory.c.  The handling of NSC was rather bogus here and was little more than a place holder, because nothing actually counted the number of 'sc' units to compare it against NSC.  A bit more work here is needed so that the scaling of SC_MAX_HISTORY_SIZE and extra_history_size goes up when more sc units are added.  But, it does not appear that we can have more than one console yet, so it does not seem particularly urgent.
