Comment (by soulseekah):

 Oh, I'm so sorry for annoying you!

 There is no redirect happening, though.

 {{{
 now try to access localhost/feed/test or localhost/feed/test/
 and you'll see https://localhost/feed/test/feed/test/
 }}}

 This does not happen on a fresh install of WordPress:

 {{{

 * Connected to stream.localhost (127.0.0.1) port 80 (#0)

 There is no redirect. My feed outputs void, just like I told it to. No
 redirects. Period.

 What am I missing? What's the actual use-case here? What's the setup?
