Thanks for rebasing/cherry-picking the series and applying my newest changes. It looks like a couple of your squashed fixes in the rebase of the old commits (designed to deal with compilation errors from the tree entry functions having been converted to object_id) went into the wrong commits, breaking bisectability. When I send out my next round, I'll only replace the top four commits, but I'll add in a few commits that can be squashed to fix the bisectability. Also, the newest patches can still be fooled by a specially crafted rename/add conflict, but I believe with a small restructure I can both simplify the code and cover all the cases.
