(WordPress snippet) Gets rid of the whitespace between "</li> <li>" in custom nav menus. Why? The whitespace can cause stupid headaches when the li's have `display: inline-block;`

no-whitespace-nav.php

<?php

// note the walker param
wp_nav_menu( array(
  'walker' => new No_WhiteSpace_Nav_Menu,
  'theme_location' => 'primary',
  'menu_class' => 'nav-menu'
) );

// in your theme's functions.php
class No_WhiteSpace_Nav_Menu extends Walker_Nav_Menu {
	function end_el( &$output, $item, $depth = 0, $args = array() ) {
		$output .= "</li>";
	}
