New wp_list_authors 'style=' fails to return author list

[michaelh]

At Revision 11521, the new 'style' argument causes wp_list_authors to return nothing when used like this:

<?php wp_list_authors('style=&exclude_admin=0'); ?>

When use like this, a list is returned:

<?php wp_list_authors('style=&hide_empty=0&exclude_admin=0'); ?>

Tested with two users, one of them admin, each with one post.

Also see #10328 for another suggested fix.

This slipped through the cracks for 2.9. Marking for early commit to 3.0.
