Put 3 words on the last line instead of 2

Thanks for the suggestion. I’m assuming this would only affect the main post content, or would you want the option for titles as well?

Just for the main post content. I think I found some kind of solution, also for the other problem with the span tag:

$(document).ready(function($){
	$('p').html(function(i, oldHtml) {
		var html = $(this).html();
		var split = html.split(' ');
		if ( (split.length > 1) && (!$(this).find('img').length) ) {
			return oldHtml.replace('<span style="color: ', '<span&nbsp;style="color:&nbsp;').replace(/(\d),\s/g, '$1,').replace(/\s+([^\s]+)$/g, '&nbsp;$1').replace('<span&nbsp;style="color:&nbsp;', '<span style="color: ');
		}
	});
});
