mkdir ZZZ
git mv stuff ZZZ/stuff             # as necessary
git commit -m "Moved stuff to ZZZ"
git checkout master
git merge ZZZ                      # should add ZZZ/ to master
git commit
git remote rm other
git branch -d ZZZ                  # to get rid of the extra branch before pushing
git push                           # if you have a remote, that is

No path specified tells git to use the current working folder.

The command cherry could be used to compare the changes in two branch.
