permalink

 Some canonical code branches are not properly accounting for extra query
 variables being specified via the url.

 For example, these url's are not handled properly:
 {{{
 /2008/?author=1 redirects to /author/admin/
 /author/admin/?year=2008 redirects to /year/2008/
 /category/uncategorized/?year=2008 redirects to /2008/
 }}}

 This happens with most date based branches, as once a higher priority
 canonical rule is hit, the permalink component is ignored.

 The canonical code includes a branch to add any "forgotten" `$_GET`
 variables back onto the url, however this doesn't help when it's the
 rewritten variables are being lost.
