changelog of the current development status, as one or more of these problems
may have been fixed since this was written!
+* libcurl doesn't treat the content-length of compressed data properly, as
+ it seems HTTP servers send the *uncompressed* length in that header and
+ libcurl thinks of it as the *compressed* lenght. Some explanations are here:
+ http://curl.haxx.se/mail/lib-2003-06/0146.html
+
+* Downloading 0 (zero) bytes files over FTP will not create a zero byte file
+ locally, which is because libcurl doesn't call the write callback with zero
+ bytes. Explained here: http://curl.haxx.se/mail/archive-2003-04/0143.html
+
* Using CURLOPT_FAILONERROR (-f/--fail) will make authentication to stop
working if you use anything but plain Basic auth.
