removed TIP: :allow_nil/:allow_blank is ignored by the presence validator
These tips were documenting an inconsistency issue https://github.com/rails/rails/issues/8621. That issue is resolved by https://github.com/rails/rails/issues/8622.
Fix collection_radio_buttons with the option `:checked` with value of
`false`
Extract the component rendering of collection_radio_buttons and
collection_check_boxes to a private method.

It will make easier to extend.

Example:

    class CollectionRadioButtons < ActionView::Helpers::Tags::CollectionRadioButtons
      include CollectionExtensions

      def render
        wrap_rendered_collection(super, @options)
      end

      private

        def render_component(builder)
          builder.radio_button + builder.label(:class => "collection_radio_buttons")
        end
    end
Make test logs easier to read.

Tagging every message in tests makes the logs really wide. It's great
for grepping, but annoying to open in an editor or a narrow terminal.
Try out a different approach: spit out a heading before each test.

rewrite order dependent test case. #8185

As reported (https://github.com/rails/rails/pull/8185#issuecomment-11702226)
this test relied on the order a hash was serialized. Comparing the parsed
hash makes the test no longer order dependent.
Fixed couple of typos

Revert "reminder to run bundle after setting up rails-dev-box"

This reverts commit 41381c19d1f3920ee9540aff0d35209cb43fb057.

Reason: This doesn't quite fit the flow where it's added. Let's add this
someplace else if it's explicitly required.

Revert "Add rake default to description"

This reverts commit 0d8ca8124de9b3a5f6398a28d79baca935a1f96c.

Reason: docrails isn't the place to do this. Also, I feel this is
not really required.
