In pure git you would have to create new branch at the commit you want
to amend, amend the commit (in this branch), and rebase (or cherry-pick
if you need to edit other commits too) the rest, then rename branch.
Or if you don't want ot loose reflog, tag/branch current branch, then reset
(rewind) current branch to the commit you want to amend, then cherry-pick.

Or you can use cg-admin-rewritehist tool from Cogito.
