In the description in the manpage: Lets you rewrite git revision history by creating a new branch from your current branch, applying custom filters on each revision. (...) The command takes the new branch name as a mandatory argument and the filters as optional arguments And in example: Now, you will get the rewritten history saved in the branch newbranch (your current branch is left untouched).

That would need the commit id for the original commit being treated at the time, which I don't think is available in parent filters...
