Editing functions: the_post_navigation();

    Am i missing some key understanding in how to make changes to some of the built in wordpress functions. I wanted to restrict the previous and next links on my site to only link to posts in the same category.

    The basic function looks like this:
    <?php the_post_navigation(); ?>

    If I split this into two functions I can set an option to TRUE so that the nav links only to same category:

    <?php previous_post_link('%link', '%title', TRUE); ?>
<?php next_post_link( '%link', '%title', TRUE ); ?>

    But when I do this I lose all the markup code around around the links, so at the end I have to replace all the divs and I get this:

    <nav class="navigation post-navigation" role="navigation">
<h2 class="screen-reader-text">Post navigation</h2>
			<div class="nav-links">
			<div class="nav-previous">
			<?php previous_post_link('%link', '%title', TRUE); ?>
			</div>
			<div class="nav-next">
			<?php next_post_link( '%link', '%title', TRUE ); ?>
			</div>
				</div>
			</nav>

    This seems like a pain in the backside to have to do everytime I want to make a small change – surely I am missing some simpler way of editing the original function? Note: I am using _s theme.

    This will work only for 4.1 and up:

    function custom_nav(){
	$navigation = '';
	$previous   = get_previous_post_link( '<div class="nav-previous">%link</div>', '%title', true );
	$next       = get_next_post_link( '<div class="nav-next">%link</div>', '%title', true );

	// Only add markup if there's somewhere to navigate to.
	if ( $previous || $next ) {
		$navigation = _navigation_markup( $previous . $next, 'post-navigation' );
	}

	echo $navigation;
}

    Reason is that _navigation_markup was introduced in 4.1.
