Or check the todo list shown to the user with

	GIT_SEQUENCE_EDITOR="cat >actual" git -c core.commentChar=% \
		rebase -i --update-refs base &&
	test_grep "% Ref refs/heads/wt-topic checked out at " actual

so that we are sure that line exists - I had a quick look and I can't 
see any existing coverage checking that the todo list contains this comment.
