git-filter-branch behavior

All,

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? Using git-rebase -i to edit the commit history works, but is a bit tedious on a large tree.

Many thanks!

Cheers, David
