Restore in-place

Hi Denis,

I'm usually doing an "online" backup with dar. This means, I create the backup while my system is running.
Example: dar -R /home/tobias/Documents -c /var/backup/documents
 
The same does usually also apply, if I want to restore some files from the backup.
Example: dar -R /home/tobias/Documents -x /var/backup/documents -g foo/file1.txt

In this way, the path where I created the backup from and the path where I want to restore the file are identically.
From a usability perspective, it would be great, to tell dar to extract the file foo/file1.txt from the given archive /var/backup/documents "in-place".
This would require dar to save the source path in the archive when creating the backup.
Is this possible with dar?
As far as I can see, there is something like that in the dar_manager.
Do you think, this option would be helpful to have in dar?

A workaround would be to use the --user-comment option to save the source path. 
But I think this is not an optimal solution.

Best regards,
Tobias
