You can always create a branch, off any commit in the DAG, as in the
previous emails,
and then replay the changes there.

But there are alternatives as well, e.g. you can also create a branch
from the tip of master,
and then remove the two old commits, and keep the last one. I usually
do this via sg like

git rebase HEAD^^^^ --interactive

which will start an editor with the 4 latest commits. Then you just
remove the ones
you don't want, save, exit, and then git will perform the rebase, as desired.
