[Bug 1386237] [NEW] tar acl support has strange behaviors

[Scott Moser]

Public bug reported:

as discovered in bug 1382632 (http://launchpad.net/bugs/1382632), tar's --acl has unexpected behaviors.
The one that caught us there was that extracting a tar file with '--acl' that was created without '--acl' results in default acl being set on the top level extracted directory.  One would expect that if the source tar file had no acl information that the extracted directory would have no 'default' acl.

I'll attach a script here that shows behavior of multiple combinations of:
  tar -c [--acl / -no-acl / default]
  tar -x [--acl / --no-acl / default ]
and source directories with acl, without acl and with default "default" acl.
