The <> in generics in hyperlinks aren't escaped (invalid HTML generated)

[Hixie]

For example, the debugDescribeChildren docs have markup like this:

<p>The list must not contain any null entries. If there are explicit null
  | children to report, consider <a href="foundation/DiagnosticsNode/DiagnosticsNode.message.html">new DiagnosticsNode.message</a> or
  | <a href="foundation/DiagnosticsProperty-class.html">DiagnosticsProperty<object> as possible <a href="foundation/DiagnosticsNode-class.html">DiagnosticsNode</a> objects to
  | provide.<p></p>

...which results in bad formatting (note the stray <object>).
