My fault for not making it more clear. I'll try to add this kind of 
information into the first mail next time.

Also that would be a horrible and very fragile method to detect an 
overwrite (files could still be overwritten; the archive would have to 
be packed correctly with a directory at the beginning to detect it 
reliable) I understand your point. Even if it is unlikely, it could be 
possible that someone tested for that behavior and maybe has problems if 
it changes.

No problem with that. I will try to be extra sensitive for problems with 
Untar that appear on the list in the next months.

Best regards
