theme_more_link() has incomplete parameter list

Currently, this theme function only takes $url and $title parameters, respectively used as $url and part of the $options array for the l() call used inside.

However, the $options parameters to l() is hardcoded to ignore any extra options, which could be passed in: array('attributes' => array('title' => $variables['title']))).

This prevents using it with any URL containing options like a query or fragment. It should merge in options received, which would also have the advantage of making it directly usable with the url/options format returned by entity_uri(). Having $title, which is only part of these options, be a direct parameter to theme_more_link(), makes is not completely obvious, but the options merging could still be done.
