Did you get the file from a git repository? These should be the original contents I believe:
PHP Code:
RewriteEngine On
RewriteCond %{REQUEST_FILENAME} !-f
RewriteCond %{REQUEST_FILENAME} !-d
RewriteCond %{HTTP_HOST} ^www\.(.*) [NC]
RewriteRule ^ http://%1%{REQUEST_URI} [L,R=301]
RewriteCond %{REQUEST_URI} !\.(js|css|gif|jpg|png|ico)$ [NC]
RewriteRule ^(.*)$ index.php [QSA,L]
RewriteRule ^get/([0-9]+).gif$ /click/siggy/$1 [L]
Then you can add those lines from that post
