New description:

 If `$_POST` is empty a canonical redirect is still made even though it
 should be ignored upon all POST requests. As this redirect occurs before
 user have a chance to handle the request themselves in a template_redirect
 filter it prevents users to write proper REST APIs that include POST
 requests with no data.

 A patch that uses `$_SERVER['REQUEST_METHOD']` instead of relying on the
 `$_POST` variable to identify request type is attached.
