Add schemeless-url helper?

[Ambrevar]

It's often useful to get the URL string without its scheme, but Quri makes it surprisingly difficult. Maybe add a helper?

(defun schemeless-url (url)             ; Inspired by `quri:render-uri'.
  "Return URL without its scheme (e.g. it removes 'https://')."
  ;; Warning: We can't just set `quri:uri-scheme' to nil because that would
  ;; change the port (e.g. HTTP defaults to 80, HTTPS to 443).
  (format nil
          "~@[~A~]~@[~A~]~@[?~A~]~@[#~A~]"
          (quri:uri-authority url)
          (or (quri:uri-path url) "/")
          (quri:uri-query url)
          (quri:uri-fragment url)))

Maybe better:

• copy the URL,
• if the port is NIL set it to the default value for the given scheme
• set the scheme to NIL

The second approach seems sounder.
