Thanks for the bug report! Indeed the error variable was shadowed,
so it was not even reported to the user. I also skip any non-regular
file during that pax-archive creation. Only directories and regular
files will be included. If someone wants any other type of files,
keeping permissions, ownership, ACLs, flags, hardlinks, xattrs, etc,
then external tar invocation must be used (that is less a problem now
because of streaming encrypted packets format).
