[wp-testers] Paging broken on Manage Posts and also affects Ticket #2578

[Ryan Scheuermann]

Couple of related bugs using the latest trunk code...

First off, the paging on the Manage Posts admin page is determined by 
the option "posts_per_page" but the results list is hardcoded to show 
the Latest 15 posts:

edit.php, line 59:

    wp('what_to_show=posts&posts_per_page=15&posts_per_archive_page=-1');


So, if I set the "posts_per_page" option to 5 (on Options->Reading) and 
I have 15 posts, the Manage Posts page allows me to page through 3 pages:

* the first page contains my latest 15 posts
* the second page (previous) is blank
* the third page (previous) is blank


The other bug is related to Ticket #2578 - Setting "Show at most N 
posts" to 0 appears to break Page display (with a 404)

If I set the "show at most N posts" to 0, the Manage->Posts page now 
displays 15 posts and this error:

*	Warning*:  Division by zero in *wp-includes\template-functions-links.php* on line *476*

+1 for not allowing this setting to be 0

Ryan, this is related to Changeset 3694 ...  I didn't quite know how to 
submit a Trac ticket for this issue since it's an issue in multiple 
places...
