Action "permalink_structure_changed" passes new permalink_structure for old and new permalink_structure value

[doublesharp]

Per the function PHPDoc, the set_permalink_structure() method in /wp-includes/rewrite.php should fire the 'permalink_structure_changed' with the old and new permalink structure after the new structure is saved:

* Fires the 'permalink_structure_changed' action once the init call has

• processed passing the old and new values

It is currently passing $this->permalink_structure as the "old" structure value, however as this value is updated by the call to $this->init() the result is that the new structure is passed instead of the old structure.

Suggested patch would copy $this->permalink_structure before the call to $this->init() and pass the copy as the old permalink structure.

Thanks for the patch! For future reference, it is preferred that patches are made from the root of the WordPress checkout, so referencing wp-includes/rewrite.php instead of just rewrite.php.

Sorry about that, still getting used to my new SVN client. I will make sure they are from the root in the future, thanks!
