Reported by Michael-O on the curl-users list: http://curl.haxx.se/mail/archive-2013-11/0038.html
The command line like:
[1/3]: http://curl.haxx.se/docs/manpage.html --> manpage.html
etc, and then download the [2/3] and then stop. The command line only specifies two versions.
This problem exists in 7.33.0 and has not been fixed since-
