To me, this all sounds like we should should revisit why precord uses
nquery at all.  If we stopped using nquery, and used query (defaulting
to the action a frontend might want), what would the user lose?
Having to type n + enter, instead of just enter to cancel, doesn't seem like
a bad deal to me.  Plus, wouldn't we want these particular offending
precord queries to default to 'y' even when in script/batch mode?

I think we should scrap out nquery from record.c, turning those to
query's, 'error's or normal stops, appropriately.  What would be missed?

There's issue of how does a frontend handle queries in a cli console
with -interpreter-exec cli (how does a frontend simulate queries
done on a a real CLI attached to a terminal), but that seems like
a mostly independent problem.
