win dirs don't handle lack of inherited rule(?): getfacl + tar dir Warning: Cannot acl_to_text: Invalid argument

I ran tar on another directory and got a huge number**
of these:
tar: rules: Warning: Cannot acl_to_text: Invalid argument
tar: adblockplus: Warning: Cannot acl_to_text: Invalid argument
tar: autopager: Warning: Cannot acl_to_text: Invalid argument
tar: bookmarkbackups: Warning: Cannot acl_to_text: Invalid argument
getfacl on one of those directories:
...>  getfacl tidy
# file: tidy
# owner: Bliss\law
# group: Bliss\lawgroup
group:Bliss\Domain Admins:rwx
getfacl: tidy: Invalid argument

actual number, out of 2658 dirs & 13207 files, got 2338
of these on what appear to only be directories.

I checked 2 of them, looking for anything strange (weird
usernames or id's), reset them and the message went away:
1) there was a null deny entry  that applied to the dir only --
   removing it didn't change anything, but started w/that as it looked odd.
2) all entries were 'dir-only', so changed one to everything
and wrote it -- and the error went away with that 1 entry (dir).

So maybe it has something to do with missing inheritable
permissions?  (a WAG).

Either way, it would seem the fix has to be in cygwin, as most apps
will get some type of error on the failing entries and besides looking
icky, it will get some wondering 'why'?  Oh well.

Don't know if that gives anymore to go on since last time -- seemed
like some of those had more to do with invalid (old hostid) entries.
