Ack. There's a bug in Dpkg parser. The comments before a Description are not
handled correctly. As a result, the comments are misplaced and the short
description is moved in the long description.

That's a side effect of the same bug.

I've tried Augeas [1]. I've created a lens that a read write dpkg file without
changing the order. But bridging Augeas with Config::Model [2] is an order of
magnitude more complex [2]. One has to maintain 2 dpkg descriptions with:
* different syntax (lens description looks like a functional language,
Config::Model is a data structure)
* subtly different semantics: 2 types of list on Augeas side vs 1 on
Config::Model side
Long story short, to preserve my sanity, I finally gave up trying to harness
these 2 beasts together.
I've some ideas on how to improve re-ordering on cme side. Before that, I need
to simplify Config::Model read/write classes (aka backends)
Thanks for the report
All the best
