If you start the structure with 'posts' instead of  '%category%',
use_verbose_page_rules should automatically be set to false.

Starting permalink structures with wildcards such as %postname%,
%category%, %tag%, and %author% means we have to use verbose rules to
avoid rewrite collisions.  Putting taxonomy tags in your structure
also means you can accidentally 404 posts when you change categories
or tags after publishing.  Plus, categories in permalinks is so early
00s, back when posts were given one category.  Now posts must be given
a full taxonomic infusion of categories and tags to be cool. ;-)
