Good htaccess suggestion for SEO

I can't take credit for this but I found it to be useful and should be part of core .htaccess file.

  #get rid of trailing slashes
  RewriteCond %{HTTP_HOST} ^(www\.)?(.*)$ [NC]
  RewriteRule ^(.+)/$ http://%{HTTP_HOST}/$1 [R=301,L]

SO:
http://www.mysite.com/news/ would redirect to http://www.mysite.com/news
before doing this both pages would appear in search index.
