Well, there's still a broken username, but that's our problem with
iso8859-1 in passwd.

Good to know, we didn't that we lost it until now :)

At the time of 2005-11-17 we'll have used a cogito and git version,
which was from 2005-11-10.

Above you see the versions of which were/are installed. I always
link the latest binaries to /usr/local/bin/, so our developers do not
need to care about what version we have.

Those were some lessons in our house. Our developers had to test
if everything works, including deleting :)

Ok. Thanks for your help! I think we'll add those four files
back to git on monday and continue to work with them.
