[RFA] print arrays with indexes

That was the reason why I asked, because I sensed some disparity between
what people wanted. In my particular case, it doesn't matter, because I
will turn the feature on on a as-needed basis, so won't use the threshold.
However, the cases where I have needed it are when the array was too big
for me to do the counting... So Jim's point makes more sense to me too.

This sounds good to me too. Perhaps a compromise between what Eli
suggested and what you have been suggesting would work. How about
we implement a on/off knob for now. Later on, if we understand better
in which direction to use the threshold, then we can enhance the knob
to include "auto", and then have a second knob.

As long as we cross-reference each setting in the help text, I think
users won't be confused.
