dojo.NodeList.addContent hangs browser

[dante]

with some node: <div id="foo">bar</div>

the NodeList? operator:

dojo.query("#foo").addContent("test");

causes FF to stop responding. the inline comments indicate "lastafter" as a second param is the default, but is seemingly ignored.

dojo.query("#foo").addContent("test","after");

works as expected.

okay that wasn't so bad

(In [11985]) ensure that the position default is actually respected. Fixes #5542. Adds better docs. !strict
