Allow more than 50 pages to show up in left-hand Navigation

We are using Publishing in our MOSS environment for our Intranet. Some of our groups are creating manuals using the publishing pages and have found that the Navigation option of automatically show all pages has a limit of 50. After the 51st page has been created and published they will not show up. We wanted to increase this number.

As described here, hereand here, I edited the web.config file on the FRONT END web server. Once saved, the changes took effect immediately. Add the part in bold below:
