CURLOPT_CUSTOMREQUEST is used to replace the literal command string
without affecting libcurl's behavior otherwise. So libcurl is acting
like it should do a download even though it's sending "rmdir /anydir" as
the FTP command.

To send custom FTP command sequences use CURLOPT_QUOTE,
CURLOPT_PREQUOTE, or CURLOPT_POSTQUOTE; you may also want to set
CURLOPT_NOBODY to indicate that libcurl shouldn't expect a download.
