Thanks for the patches!

The --clamp-mtime options looks primising, but I'm not happy about its
current situation. Please get this upstreamed first. I don't mind making
dpkg depend on an extremely recent GNU tar, but I really don't want to
use a Debian specific option like this, as it could change semantics,
etc. And I don't like parsing --help output at all. I still have to fix
the situation with dpkg-source using the Debian specifi gzip --rsyncable
option, for example. :(
