Allow element between li's but not after final element in wp_list_bookmarks

[in2thats12]

Many times when displaying a list, one wants a separator between the list elements. Using the "after" arg would cause the separator to be displayed after the last element also.

To this end, I added the "li_between" option to the _walk_bookmarks function which places the contents of "li_between" after each list element, but not after the final list element.

Patch attached.

This opens up a rabbit hole of inconsistency, with so many walkers and li's throughout WP.

This seems like something that should be done through CSS. Keep in mind you have last-child and plenty of other ways of selecting elements.

List items cannot have other siblings than list items. Anything else is invalid markup:

<ul>
  <li>
  <hr> <!-- invalid -->
  <li>
</ul>

Why should WP help to create broken HTML?
