Added a support comment, and updated spacing

As discussed in #1597.

Yes, with the `try...catch`

Again, that is not related, it never was.

I had reproduced already, in order to do so, you need change `document.domain` property and set "local intranet" security zone in IE6/7, only than you would get described error in http://bugs.jquery.com/ticket/8138. 

What you are trying to show is nothing new and is not relevant to this workaround
