IOWs, I am experimenting with something like:

git filter-branch -f -d /tmp/moodle-$RANDOM --prune-empty --index-filter "git ls-files -z | grep -zZ -v '${dirpath}' | xargs -0 --no-run-if-empty -n100 git rm --quiet --cached --ignore-unmatch " ^v2.1.0 $branches git filter-branch -f --prune-empty --subdirectory-filter ${dirpath} ^v2.1.0 $branches git filter-branch -f --commit-filter "~/src/git-filter-branch-tools/remove-pointless-commit.rb \"\$@\"" ^v2.1.0 $branches

perhaps the docs for filter-branch imply, to me at least, that it's a DWIM tool. I am surprised at having to roll my own on something that is fairly popular.

cheers,
