The problem is, that when you have 'foo/bar' branch, then you have
'foo/bar' reflog. When you delete branch 'foo/bar', but do not delete
'foo/bar' reflog (only add to it branch deletion event), and then you
want to create 'foo' branch, git wouldn't be able to create reflog
fo 'foo' because of directory / file (D/F) conflict: there is 'foo/'
directory preventing file 'foo' from being created.

That is a good idea anyway.
