a links fail to work

this is a dup of #2158

But..... seems counter-intuitive to have to set the header option just to have links in the accordion.

in the jqueryui docs http://docs.jquery.com/UI/Accordion/accordion#options it says ..

Default: '> li > :first-child,> :not(li):even'

but

in ui.accordion.js

$.extend($.ui.accordion, {
	version: "1.6rc6",
	defaults: {
...
		header: "a",
...
	},

i spose its hard as you don't want to break old installs,

the "default" (according to the docs) doesn't work on mine

<li>
 <a href="#">Link</a>
 <div>
   content
 </div>
</li>

The default was changed to '> li > :first-child,> :not(li):even' after the 1.6rc6 release.
