edit_todo_list() is changed to work on a todo_list, and to handle the
initial edition of the todo list (ie. making a backup of the todo
list).
It does not check for dropped commits yet, as todo_list_check() does not
take the commits that have already been processed by the rebase (ie. the
todo list is edited in the middle of a rebase session).
