Tar never creates user when extracting. It should just treat whatever

Call them broken, but still such implementations exist :-( ... I had
some trouble on an older HP system, where a tar created files owned by
user number -1, if the untared user name contained UTF-8 characters ...
files that even root couldn't access or delete!
I would call that even more broken. I would even know how to create
files with owner -1, as chown(-1) doesn't change the owner.
But I won't send files with such names to other people.
