Category/tag URL changed if the permalink structure has static strings

[lilyfan]

The category/tag URL of WordPress 2.6 changed from 2.5.1 if the permalink structure has static string.

(Example)
Permalink structure is "/arc/%year%/%monthnum%/%day%/%postname%/", and WordPress is installed at ​http://example.com/

Category URL of WP 2.5.1: ​http://example.com/category/foobar/
Category URL of WP 2.6: ​http://example.com/arc/category/foobar/ (The static string "arc/" is added at URL)

There is no way to force "​http://example.com/category/foobar/" at WordPress 2.6. This is unwanted behavior.
The category/tag URL is needed to keep same as long as the author wants, such as permalinks.

Please keep back the category/tag URL structure to WP 2.5 way.

Perhaps related to [8366]. Have you tried 2.6.1 beta 1 to see if it fixes the problem?

[lilyfan]

I used 2.6.1 beta 1 and met the problem. I think that "2.6.1 beta 1" has the this problem yet.

Patch for 2.7 (trunk)

Testing with and without custom category and tag bases. Working well so far.

(In [8616]) Do not prepend /archives/ et al to category/tag URLs unless category/tag slug is missing. fixes #7490 for trunk
