New Revision: 4868

Modified:
   plog/branches/lifetype-1.2/class/template/smarty/plugins/function.pager.php
Log:
Small usability improvement to the pager: added an "anchor" parameter that will be appended to each link to a page, so that we can get the browser to jump to that anchor in case the content doesn't start exactly at the top of the page.
