Running
git-filter-branch --tree-filter 'rm -rf subdir/' -- --all
as shown below seems to leave empty commits
corresponding to subdir/ in the tree. Is this the expected
behavior? If so is there a command to remove the empty
commits?
The following is probably overkill, but it is what I would do.
It's completely untested. If you'd prefer to do things by hand
instead, my only advice is that using grafts with filter-branch
might be easier than rebase -i.

test "$#" -eq 1 && interesting=t
committree=$1
shift
for sha1 in "$@"
do
test z"$sha1" = z-p && continue
map "$sha1" | while read parent
do
parenttree=$(git log -1 --pretty=format:%T "$parent")
test "$committree" != "$parenttree" &&
interesting=t
test -n "$interesting" && break
done
test "-n interesting" && break
done
test -n "$interesting" && git commit-tree "$@" || skip_commit "$@"
You may want to pass the tree to be committed here ;)
I.e.:
git commit-tree $committree "$@"
etc.
