Move a commit to another branch

To move the last commit(s) to another branch, first make a new branch (this will include the commits from the current branch):

git branch newbranch

Remove the unwanted commit(s) from the current branch (the command below just removes the latest commit):

git reset --hard HEAD^

To remove N commits, you can use:

git reset --hard HEAD~N

Now newbranch has the new commit(s) while the current branch no longer does.
