Yep. I'm wondering how this should be formatted - something like 0 (2) maybe?

The implementation looks relatively straightforward from what I've already seen of the code. But while working on other changes, namely an integrated Anti-Kibitz script that works under IE, I have discovered that it's non-trivial to write unit tests for things like how a single comment is rendered. The design of the Reddit codebase has some rough spots, like the use of globals for HTML rendering.

It's the sort of thing that could be done without tests but that I'd hate to do without tests because that would be adding to a technical debt which has already grown into the danger zone. That takes it from straightforward to moderately hard.
