  * owner:  anonymous => pishmishy
  * status:  new => assigned
  * summary:  @ character stripped from mailto link, http:// inserted in
              string => clean_url() not working for non-HTTP
              URLS

Comment:

 The following code from clean_url() strips @ from URLs.
 {{{
 $url = preg_replace('|[^a-z0-9-~+_.?#=!&;,/:%]|i', '', $url);
 }}}

 The following code from clean_url() prepends http:// onto non-http URLs
 {{{
 if ( strpos($url, '://') === false &&
                 substr( $url, 0, 1 ) != '/' &&
 !preg_match('/^[a-z0-9-]+?\.php/i', $url) )
                 $url = 'http://' . $url;
 }}}
