limit blog list to users who have blogging permission

My site has thousands of users who do not have permission to blog, but the module showed them as having blogs anyway, so the list of feeds was really really long (so long the page timed out) for no reason. I changed line 591 to

$result = db_query('SELECT u.uid, u.name FROM {users} u join {users_roles} r on u.uid = r.uid join {permission} p on r.rid = p.rid WHERE u.status = 1 and p.perm like "%own blog%"');

and now only the users who have blogging permission are listed as having blogs. It's a small thing, but it makes the module much more usable. :-) Thanks for all you do.
