I get distracted (by work...) for the afternoon, and things take an 
unexpected turn!

I definitely did not mean to throw open the floodgates to reconsider the 
entire -O switch.  I agree that the -O switch seems like too much UI for 
too little change in results, and I think a different set of settings 
and defaults makes more sense.  But I do not suppose that we have much 
appetite to take on that large a change.

For my purposes, an environment variable and no change or addition to 
the switches would be fine.
