The reason is that altough "." was too old to make it into the archive, it made 
it into the hardlink cache. Any second attempt to archive "." will make it a 
hardlink if -link-dirs is used. The workaround for this problem only would be 
simple. The workaround for the fact that the current test version does not 
force to archive "." in case that VOLHDR=xx has been used needs a new idea...

Maybe, I already have it.

But I am not sure when I will be able to hack this, give me some days.
