I recently moved a blog from mydomain.com/blog to mydomain.com using the guide in teh codex.
At first, the move seemed just fine, but then I realized that mydomain.com/blog now redirects to the oldest post I'd written whose slug begins with "blog".
I use the /%year%/%monthnum%/%day%/%postname%/ permalink structure.
a) Is there a way to prevent mydomain.com/full from redirecting to mydomain.com/year/mo/dy/full-slug
b) Is there a clean way to always redirect mydomain.com/blog to mydomain, so users don't get confused by a 404.
