Why would tar create any acls if there are none in the source tar?

I saw someone else have a similar complaint about acls being created
when the tar didn't have acls but the --acls option was used.

I wouldn't want a non-acl containing tarball to overwrite or change
default acls in a directory that already exists.

I wouldn't want acl="undef" to overwrite a set value.

I just was working on a parameter passing routine -- and had
to think -- did I really want "undef" (in perl) to overwrite
a defined value?

If I said --acl=reset or similar, that might be a desirable feature.

But I use default acls and certainly wouldn't want them cleared as a
normal action when there are no replacing acls specified.
