Comment (by caitrionad):

 +1 for being able to modify the innards of gallery_shortcode - I
 frequently find myself wanting to add a class to a gallery item while
 continuing to use the rest of the standard implementation.

 The solutions above were helpful in achieving that but I'd love if there
 were a cleaner way.

 BTW, re. using `wp_get_attachment_link` to modify a gallery item's link,
 there is a way to apply that solely to gallery attachment links:

 {{{
 add_filter(
     'post_gallery',
     function(){
 add_filter('wp_get_attachment_link','custom_modify_gallery_shortcode_link');
     }
 );
 }}}
