[chencc98]

the first demo on the page http://api.jquery.com/all-selector/ is wrong. there should be only 10 elements found.
please check.

I don't think this is an error, but I did update the documentation with a warning:

"Note that if your browser has an extension/add-on enabled that inserts a <script> or <link> element into the DOM, that element will be counted as well."
