Below is the format_text patch I worked on a long time ago based on Klaus' suggestion. I wasn't able to contribute it back then, but can now.
It is built against and old version of audit. I can create a similar patch against the latest level if it would be helpful.

Hi Debbie & Mounir,

Debbie, thanks for working on this and being so quick to get it done. I really
appreciate that. I'm not so happy that I can't publish your contribution.

In short, I have to release a new version of audit today. I'm attaching
Debbie's patch to this e-mail. Its a diff between 0.6 and 0.5.7 - which was
my development copy that was never published. This will let you "put it back"
for testing.

Thanks,
-Steve Grubb
