That's funny. I looked at the output on (what I thought was) a small repo and it was showing me 9-character abbreviated hashes. I guess I just got lucky. Tested on a basically empty repo and 7 does look to be the default. > PS As you noticed, "git log" we don't promise that git-log output will > never change between versions.

My mistake was thinking that the `--raw` made the `git log` output somehow more plumbing-ish, but I've gone ahead and switched to using git-rev-list plus git-diff-tree instead. Anyway, patch follows.
