jQuery .nextUntil() equivalent
<p>I need an alternative for jQuery's <code>.nextUntil()</code>. I'm currently using <code>jQuery 1.3.1</code> and updating it is out of the question :(</p>

<p>I have this HTML:</p>

<pre><code>&lt;h4&gt;...&lt;/h4&gt;
&lt;p&gt;...&lt;/p&gt;
&lt;p&gt;...&lt;/p&gt;
&lt;p&gt;...&lt;/p&gt;
&lt;h4&gt;...&lt;/h4&gt;
&lt;p&gt;...&lt;/p&gt;
&lt;p&gt;...&lt;/p&gt;
</code></pre>

<p>and I have this jQuery code:</p>

<pre><code>$('h4').click(function(){
    $(this).nextUntil('h4').toggle();
});
</code></pre>

<p>but <code>.nextUntil()</code> is added in <code>1.4.0</code> So do you have an idea how to do that in <code>1.3.1</code> ?</p>
