alt and title attributes of logo

Hi there,

I suggest to change a part of the code in the file page.tpl.php. The part if of the alt and the title attributes of logo. If I don't want display the site name or the slogan, I have a void alt and title attributes.

This is the original code:

<img src="<?php print $logo ?>" alt ="<?php print $site_name_and_slogan ?>" title="<?php print $site_name_and_slogan ?>" id="logo" />

I suggest to change it in this:

<img src="<?php print $logo ?>" <?php if ($site_name_and_slogan): ?> alt ="<?php print $site_name_and_slogan ?>" title="<?php print $site_name_and_slogan ?>" <?php endif ?> id="logo" />
