I guess this depends on whether you consider the brainstorming and
discussion to be part of the work of polishing, and I do mean polishing.
 Getting from something that works 90% of the time to something that
works 99% of the time can be a questionable expenditure of time and effort.

I did rewrite our merge code once, but that was because the API was
quite hard to deal with and made it hard to maintain.  I agree that it's
important to focus effort on the areas that make a difference.

On the other hand, our "exotic" text merge algorithms have been praised
by the people who work on Launchpad.  So that's a win.

Yes, I don't even want to think about CVS when I don't have to.
