em tags in title attributes of links in the block

Issue Summary

The links come up with a title attribute as
title="view <em>Post Title</em> in full"
The em in the title attribute does not make sense. This was because of an error in the theme_taxonomy_block_list_item function. I have corrected the code and am posting it here. The only change is in the %variable in the t function which was changed to a @variable.

/**
* Format a single item for a list.
*
* @ingroup themeable
*/
function theme_taxonomy_block_list_item($node, $teaser) {
$output = '

';

return $output;
}
