I reviewed the changes -- last ones 'cursory' as I think those don't 
break any "real" functionality -- and if help works bad then one can

...but I did not test -- automated tests (to ensure it doesn't break
anything be handy... more complete would limit anyone's interest to
implement alternate option handling (even further).

As much I also liked "better" option handling code new code (vast of that)
would also require significant reviewing effort which no-one will like

With that said, +1 from me to the config handling changes. 
(or should I give it some hand-testing (how?)
