wp_delete_term should allow you to force a new term to be applied to all objects

[westi]

This makes it easy to merge categories or tags from a plugin

Example usage of feature

wp_delete_term(5,'category',array('default' => 4, 'force_default' => true));

Deletes category id 5 and sets all posts to be in 4.

(In [10813]) Allow wp_delete_term users to force all objects to have a new term applied. Allow for category merging use-case. Fixes #9355.

It's already marked as fixed but I just wanted to confirm that this works as intended. Thanks so much for the fast work westi!
