Thanks for the input regarding wording. I'll let the thread sit for a
while so people can comment, but if I don't hear anything, I'll go ahead
and commit the wording change in a couple of days.

If you are looking for parsability, the '--xml' switch does provide the
nesting you want, and it is designed to be a bit more parsable than the
standard output.
