blog_prefix is set to blog for permalinks

Hi,

In a new wordpress install, I have ” /blog “

hard coded to the left of the field “Custom Structure” for permalinks. I would like to have /blog removed.

The problem is in the file:

/public_html/wp-admin/options-permalink.php

The blog_prefix is set to blog in the file and I am not sure how to delete it because I do not understand php. And I don’t want to remove any code that may break other sections of the php.

What line(s) of code do I remove specifically and how can I prevent this apparent default setting for future installs of WP?

Thanks
