OK, slightly modified to prevent the function from messing with dots (.) and return the result instead of echo:

function removedoubles($string){

$string = preg_replace("/([,?!])/"," 1",$string);

$parts = explode("/",$string);

$unique = array_unique($parts);

$unique = implode("/",$unique);

$unique = preg_replace("/s([,?!])/","1",$unique);

return $unique;

}

This applied to function next_posts and previous_posts in /wp_includes/link_template.php:

function next_posts( $max_page = 0, $echo = true ) {

$output = removedoubles(esc_url( get_next_posts_page_link( $max_page ) ) );



if ( $echo )

echo $output;

else

return $output;

}

This works. Changes in core files is not ideal of course, so I’ll probably have to copy a lot of code and turn it into a custom version in functions.php.

Or is there a cleaner way? Is it possible to put something in functions.php that “catches” any calls for function previous_posts() and redirects them to a function custom_previous_posts() in functions.php?
