Attaching patch against Debian unstable. For ease of review, relevant
commits and tags have been pushed to the following repository:

https://code.launchpad.net/~waveform/ubuntu/+source/lvm2/+git/lvm2

Specifically:

* logical/2.03.16-1ubuntu1 represents our split-out delta on
  top of old/debian (2.03.16-1)
* logical/2.03.16-2ubuntu1 represents our rebased delta on
  top of new/debian (2.03.16-2)
* merge/2.03.16-2ubuntu1 adds changelog and maintainer
  changes on top of logical/2.03.16-2ubuntu1

Hence, the following command may produce output useful to the purposes
