Hi,

--archives is the default, which solves most of the problems you
describe. The only known problem that remains is support for alternative
compression methods (gz and bzip2 are supported, but xz is not supported).

If you report bugs, please use reportbug, as the upstream version only
makes it hard to know whether we talk about the same package version.

Bye
Willi
