htaccess bug with WP in subdir

Ohai, I think I found a bug in the .htaccess file generation when the wp install resides in a subdir in htdocs dir.

like http(s)://subdomain.domain.tld/wordpress/

While all checkmarks in the settings tab are green it still complains about failed queue queries, which I can see as 404s in the server log.

Manually “patching” the rewirte rules solves the problem, but generates warnings regarding incorrect .htaccess contents.
