Godoc uses go/doc to convert comments to HTML [1], and go/doc has no
markup for lists [2].  With the previous comment, the lack of
paragraph-splitting lines between the list entries was leading to
entries 0, 1, etc. being formatted as a single paragraph.  And the
hanging indents for entry 3, etc. were leading to formatting within
<pre> blocks:

  $ curl -s https://godoc.org/k8s.io/apimachinery/pkg/runtime | grep -B1 -A7 'Your API objects'
  <p>
  0. Your API objects have a common metadata struct member, TypeMeta.
  1. Your code refers to an internal set of API objects.
  2. In a separate package, you have an external set of API objects.
  3. The external set is considered to be versioned, and no breaking
  </p>
  <pre>changes are ever made to it (fields may be added but not changed
  or removed).
