A jQuery "widon't" snippet

In the interest of more attractive Internets, here's a quick little javascript "widon't" snippet—written in jQuery—that I've been using. Now go do something cool with it.

jQuery(function($){
 
$('h1,h2,h3,li,p').each(
    function(){
        $(this).html($(this).html().replace(/\s([^\s<]+)\s*$/,'&nbsp;$1'));
    }
);
 
});

Feel free to replace or augment the selector ('h1,h2...p') with any additional elements you'd like to see widon'ted.

I actually use this variant, which lets longer words be widows if they wanna:

jQuery(function($){
 
$('h1,h2,h3,li,p').each(
    function(){
        $(this).html($(this).html().replace(/\s([^\s<]{0,10})\s*$/,'&nbsp;$1'));
    }
);
 
});

Note: Dave Cardwell posted a jQuery widon't a couple of years ago, but holy balls it's big... If you want something a bit more robust, be sure to check his out.

Another note: I added newlines and tabs to make the code more readable. If I were you, I'd remove those bad boys before deploying.

Update: I wrapped the snippets in a DOM ready callback, making it easier for those who just want to copy/paste these snippets into their site.
