Comment 1 for bug 1987340

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/2.03.11-2.1ubuntu4 represents our split-out delta on top of old/debian (2.03.11-2)
* logical/2.03.16-1ubuntu1 represents our rebased delta on top of new/debian (2.03.16-1)
* merge/2.03.16-1ubuntu1 just adds changelog and maintainer changes on top of logical/2.03.16-1ubuntu1

Hence, the following command may produce output useful to the purposes of review:

git range-diff old/debian..logical/2.03.11-2.1ubuntu4 new/debian..logical/2.03.16-1ubuntu1
