Git does not track directories but bends backwards to make empty
directories go away.  I do not know if it is an operator error
or not, but it appears sometimes it does not bend hard enough.

Interestingly enough, this seems to do things more carefully.

	$ ...
	$ git commit -m 'Add file'
        $ git branch OLD
        $ ...
        $ git commit -m 'Add a/b/c/foo'
        $ git checkout -b bogo
        $ git checkout OLD
