Hi Sergey,
If one unpacks a tar-archive using the option --one-top-level and the
archive contains an entry like
./
than the current working directory get the permissions (and the date)
of that directory in the tar archive file.
This was fixed on 2015-11-21 (commit e4267874540f306b2b2b10cab43f50b2f93aadbe).
Good to hear that.
Bad that I didn't find that information by googling and searching
on http://lists.gnu.org/archive/html/bug-tar/.
But a little bit irritating that such a (in my eyes) severe bug remains
for such a long time unfixed in the latest official release. By the way,
GNU tar 1.28.90 works as expected correctly in my application cases.
Thanks
Jens
