the multi interface, which currently doesn't work because of how the data connection is not waiting for connect before it tries to do proxy magic.
If the CURLOPT_PORT option is used on an FTP URL like "ftp://example.com/file;type=A" the ";type=A" is stripped off. I added test case 562 to verify, only to find out that I couldn't repeat this bug so I hereby consider it not a bug anymore!
