> What about adding this, but then commenting the actual option out...

*All* of the config options here are commented out (via the `=begin` and `=end` markers).  A while ago in #796 we had a big discussion and came to the conclusion that generally speaking, the only things in `spec_helper` that should be uncommented-out are things that will become defaults in future rspec releases (e.g. the `treat_metadata_keys...` option fro 2.x).  We use commented out options in the generated `spec_helper.rb` to indicate settings we recommend.
