Its been pointed out to me that this change is an intended change in
behaviour to make the recursion option positional which has broken
dpkg-deb.

I'd like to mention the commit message for this change is horrible, it
doesn't explain the real problem, or that there is a behaviour change
which is intended. Might be food for thought for future commit messages.

I'll talk to the dpkg upstream about getting this fixed there.

Cheers,

Richard
