#19896: Non-WP rewrites not saved on a multisite install

 Priority:  normal         |  Milestone:  Awaiting Review
Component:  Rewrite Rules  |    Version:  3.0
 Severity:  normal         |   Keywords:
---------------------------+-----------------------------
 The following code adds a rewrite rule which is classed as a non-WP
 rewrite rule because its redirect doesn't begin with `index.php`, and is
 stored in the `non_wp_rules` member variable of the `WP_Rewrite` class.

 {{{
 function my_rewrite() {
         add_rewrite_rule( 'login/?$', 'wp-login.php', 'top' );
 }
 add_action( 'init', 'my_rewrite' );
 }}}

 On a single site install, this rewrite rule gets saved directly to the
 .htaccess file rather than being added to WordPress' internal rewrite
 array.

 On a multisite install, this doesn't happen and the rewrite rule has no
 effect (probably because once a site is multisite-d WordPress no longer
 writes to .htaccess). The rule has to be manually added to .htaccess.

 Likely introduced in 3.0, reproduced in 3.3 and trunk.
