[Plugin: WP-Paginate] Wrong number of pages

Hi Eric,

Please check
http://wordpress.org/support/topic/plugin-wp-paginate-wrong-number-of-pages-for-archive?replies=3

I also faced this issue, with custom pages templates as well as single.php, author.php etc. As per the wordpress logic:

$pages = intval(ceil($wp_query->found_posts / $posts_per_page));

It should create 20 pages, while wp_paginate is creating 27 pages. This issue occurs specifically when I am adding filtering arguments to wp_paginate.
