When downloading a file from FTP with the -R option, curl stores the
Last-Modified-Since header in the downloaded file. This isn't fixed in
the latest daily snapshot.

Example :

$ curl -R -O ftp://ftp.free.fr/mirrors/ftp.mandrake-linux.com/Mandrakelinux/devel/cooker/i586//media/main/media_info/MD5SUM

$ cat MD5SUM
