Frankly, I have no idea where this trade is going.
With a 6 line pre-processor, you can feed the grep-dctrl
provided Description fields to Markdown. So, seems like we have come
somewhere -- we have had one investigation that leads one to believe
that there are a small fraction of packages using "o" as a bullet that
need to be changed, and apart fro that there are less than 50 packages
are affected (if we want to specify markdown as the markup language for
descriptions -- and these are the one where we have some unwanted
emphasis, a non-fatal result).
There is a mechanism to pre-process the description for
markdown (Perl implementation below). What more is needed for you to
think this is leading somewhere?

*Sigh*.
All I am doing with the code is inserting a line before the
lists. I am not generating html. I am not also handling the _other_
markup that markdown handles, that I presented as something that will
make the description more readable too. The markdown librarys does all
the heavy lifting fro the html generation. If you think my little perl
snippet is the equivalent for what markdown does, you have not looked
at markdown.
I am not re-inventing the wheel when it comes to markup
languages.
We know we needed _some_ pre-processing because we have the
paragraphs separated by ' .', but the code is pretty minimal.

<p>Description: configuration and management utilities for Apple AirPort base
stations
This package contains various utilities to manage the Apple AirPort base
stations.</p>
<p>Be aware that Apple released several versions of the AirPort base station;
the original AirPort ("Graphite") was a rebranded Lucent RG-1000 base
station, doing 802.11a/b. The AirPort Extreme ("Snow") is an Apple-built
802.11a/b/g base station.</p>
<p>For the original Apple AirPort and the Lucent RG-1000 base stations only:</p>
<ul>
<li>airport-config: base station configurator</li>
<li>airport-linkmon: wireless link monitor, gives information on the wireless
link quality between the base station and the associated hosts</li>
</ul>
<p>For the Apple AirPort Extreme base stations only:</p>
<ul>
<li>airport2-config: base station configurator</li>
<li>airport2-portinspector: port maps monitor</li>
<li>airport2-ipinspector: WAN interface monitoring utility</li>
</ul>
<p>For all:</p>
<ul>
<li><p>airport-modem: modem control utility, displays modem state, starts/stops
modem connections, displays the approximate connection time (Extreme only)</p>
<ul>
<li>airport-hostmon: wireless hosts monitor, lists wireless hosts connected
to the base station (see airport2-portinspector for the Snow)</li>
</ul></li>
</ul>
