     Should this really be made the new default?  OK, Corinna is on board
with that.  I personally don't want it as a default because I want to see
command line arguments.  Easy for me to get different, but only knowing
how.  That leads to the next question.
     Given that silent were made default, it is a big change in terms of
what people see.  How would you know to change it?  (New feature, most
people are far from experts in automake.)  Therefore, the directions most
definitely would need something added that explains it.  (Without knowing
about it, I can see it taking someone a long time to chase down why they
suddenly lost the make output.)  Something along the lines of Jon's
explanation in the patch email needs to end up in README and probably also
printed by a configure help.
