I've never seen this in any jQuery docs I've read; nor, have I ever seen it in the wild. I just observed multi-content syntax working here with jQuery 1.4.2. Is this supported syntax? Is it deprecated?

$(".section.warranty .warranty_checks :last").after(
  $('<div class="little check" />').click( function () {
      alert('hi')                                       
  } )                                                   
  , $('<span>OEM</span>')  /*Notice this (a second) argument */    
);                                                      

I've never seen any indication in the jQuery grammar that any of the functions accept more than one argument (content) in such a fashion.
