Why is that messy?

With libcurl, the whole API is designed to do one transfer for each call to
curl_easy_perform(). Each dir listing means a transfer.

You cannot make data transfers with the *QUOTE options, as that would require
that they could parse the responses and start data connections and transfers
and more.
