It's unfortunately not so easy.  The problem you have to solve is D/F
conflict: if you have 'foo/bar' branch, you can't create 'foo' branch,
but after deleting 'foo/bar' you want to be able to create 'foo'
branch and reflog for 'foo' branch.

Thanks for the pointer.  Here are some more, for the interested.
