The goal of the change is to make it easier to hook `gem` up to shell
scripts, for example:
gem install rdoc
gem list | xargs gem rdoc --ri --rdoc
Do you run this usually like `gem list -b`? I could add a special
case for that.

Alternately, if you run `gem list -r` and `gem list -l` separately,
you shouldn't need to parse anything.
