I'll look into that. Hmm..maybe before I get ahead of myself, I should back up for a second. Which way do we think is better -- handling this in cache_tree_update() or doing a fixup in commit_tree()? If the latter, then I should just drop my 7/15 and 8/15 for your 13/17 and 14/17. If the former, then it makes sense to look into this change you suggest. In that case, we'd probably keep my 7/15 but drop 8/15 for patch(es) that implement your idea above. But you're more familiar with the index format than I am and it's your idea, so you'd probably be the better one to implement it. Thoughts?
