Changelog
+Daniel S (26 September 2007)
+- Max Katsev reported that when doing a libcurl FTP request with
+ CURLOPT_NOBODY enabled but not CURLOPT_HEADER, libcurl wouldn't do TYPE
+ before it does SIZE which makes it less useful. I walked over the code and
+ made it do this properly, and added test case 542 to verify it.

URLs ending with a slash properly (it should list the contents of that
